1.1 What is Solar PV energy ?

1.2 Solar PV system components ?

Solar photovoltaic system or Solar power system is one of renewable energy system which uses PV modules to convert sunlight into electricity.[1]

Solar PV system includes different components that should be selected according to your system type, site location and applications. The major components for solar PV system are solar charge controller, inverter, battery bank, auxiliary energy sources and loads (appliances)[1]

The electricity generated can be either stored or used directly, fed back into grid line or combined with one or more other electricity generators or more renewable energy source. Solar PV system is very reliable and clean source of electricity that can suit a wide range of applications such as residence, industry, agriculture, livestock, etc.[1]

1.2.1 PV module : converts sunlight into DC electricity[1]

1.2.4 Battery : stores energy for supplying to electrical appliances when there is a demand.[1]

1.2.2 Solar charge controller : regulates the voltage and current coming from the PV panels going to battery and prevents battery overcharging and prolongs the battery life.[1]

1.2.5 Load : is electrical appliances that connected to solar PV system such as lights, radio, TV, computer, refrigerator, etc.[1]

1.2.3 Inverter : converts DC output of PV panels or wind turbine into a clean AC current for AC appliances or fed back into grid line.[1]

1.2.6 Auxiliary energy sources : is diesel generator or other renewable energy sources.[1]

1839

First solar cell is invented

1973

The oil crisis

1998

Scientists now know that collecting solar energy on a large scale is a real possibility.

The 1973 oil crisis leads people to invest in solar research.

Exxon, designs a cheaper solar panel, bringing the price down from $100 per watt to $20 per watt.

Inventor and scientist Subhendu Guha invents the first flexible thin-film product labeled as a solar shingle for BIPV use.

1941

The Photovoltaic Effect is discovered This effect allows people to make electricity from light with certain materials.

1905

03

1954

Einstenin publishes information on the photovoltaic effect

Solar cells improved to 6% efficiency by Bell Labs

Einstein goes into further detail explaning how photovoltaic effect actually works. This allows other scientists to better understand and us it.

Solar panel efficiency continued to improve over the next several decades, making solar panels much more affordable.

BIPV system

1980 ARCO Solar becomes the first panel manufacturer to hit 1 MW of yearly production. Through a series of acquisition over decades, ARCO eventually becomes SolarWorld.

2007

The first commercial CIGS thin-film modules Nanosolar ships the first commercialized CIGS thin-film modules. The company estimated it was the world’s lowest-cost solar panel at the time at $0.99/W.

Figure 4. Basic layout diagram of a hybrid solar inverter with DC battery system

DC coupled systems have been used for decades in off-grid solar installations and small capacity automotive/boating power systems. The most common DC coupled systems use solar charge controllers (also known as solar regulators) to charge a battery directly from solar, plus a battery inverter to supply AC power to the household appliances.[4]

Advanced AC coupled systems are often used for larger-scale off-grid systems and use a string solar inverter coupled with an advanced multi-mode inverter or inverter/charger to manage the battery and grid/generator. Although relatively simple to set up and very powerful, they are slightly less efficient (90-94%) at charging a battery compared to DC coupled systems (98%). However, these systems are more efficient at powering high AC loads during the day and some also can be expanded with multiple solar inverters to form micro-grids.[4]

AC coupled batteries or simply ‘AC batteries’ are a relatively new evolution in battery storage for grid connected homes and allow batteries to be easily AC coupled to a new or existing solar installation. AC batteries consist of lithium battery modules, a battery management system (BMS) and inverter/charger all in one compact, simple unit which can be easily connected to most homes.

Hybrid systems can be described as a grid-tie DC coupled solar battery systems. They come in many different configurations and typically use a hybrid or multi-mode inverter.

Modern hybrid inverters incorporate high voltage MPPT controller/s and battery inverter/chargers inside a common unit.

The first generation hybrid inverters were compatible with 48V lead-acid or lithium battery systems, however over recent years higher voltage (400V+) battery systems have become increasingly popular.[4]

These systems are generally only designed for grid-connected homes, not off-grid homes, as the (transformerless) inverters are typically not powerful enough to run a home completely off-grid and cannot handle the surge loads of many appliances.[4]

2.2 Renewable energy market Renewable energy has rapidly been making inroads into the global energy market in the past few years. Last year, global investments in renewable energy were more than double the amount spent on new coal and gas-fired plants. The sector today employs 8.1 million workers globally, and 2.8 million of them are engaging in the production of solar modules. The International Energy Agency predicts that solar energy will account for over 5% of the global power production capacity by 2020.[5]

2.1 Vision 2030 & Solar energy era A solar sector is emerging as part of Saudi Arabia’s economic diversification plans under the Vision 2030. Rising domestic oil consumption, young citizens’ entry into the job market, and reduced solar panel production costs have driven the launch of the solar industry in the kingdom. Growth of the industry had previously been hindered by institutional ambiguity and fragmentation, but the government restructuring in May has paved the way to its eventual rise by unifying necessary administrative functions under the newly-created super-ministry.[5]

06

Vision 2030 identifies renewable energy as one of the pillars of economic diversification away from oil. It sets an “initial target” of producing 9.5 gigawatts (GW) of power from renewable energy. The projects will be pursued under the “King Salman Renewable Energy Initiative,” details of which are expected to be announced soon.

The National Transformation Program 2020, which was announced in early June following the Vision 2030, set the target of 3.45GW, or 4 % of the total power consumption, by 2020. The program also aims to employ 7,774 workers in the renewable and nuclear energy sectors combined by 2020.[5]

With energy costs and consumption rising at an exponential rate, the need for renewable energy has never been greater. In accordance with the Saudi Vision 2030 plan for energy diversification, Sun Capture brings high quality, cost-competitive solar products to help businesses ease the burden of the high cost of energy.[6]

35%

As part of Saudi Vision 2030, the government has set a goal to diversify energy in the Kingdom to meet rising demands – and to cement Saudi Arabia’s position as a global energy power.[6]

drop in cost of solar PV power since 2009

growth of solar PV power worldwide in 2017

Under the new leadership, new players have begun to be promoted in the Saudi solar industry. In July 2015, an announcement was made that the country’s first solar power plant will be set up in al-Aflaj, near the capital city, Riyadh. This planned 50MW solar power plant will be created through the cooperation of three institutions: Saudi Technology Development and Investment Company (Taqnia), Saudi Electricity Company (S.E.C.), and the King Abdulaziz City for Science and Technology (K.A.C.S.T.).[5] Taqnia entered the solar industry in 2014 through its 50 percent acquisition of Sun & Life, a developer involved in Saudi Aramco’s 10.5MW solar project.[5]

3.5 Determine power consumption demands

3.6 Size the PV modules

3.6.2 Calculate the number of PV panels for the system

The first step in designing a solar PV system is to find out the total power and energy consumption of all loads that need to be supplied by the solar PV system as follows:[1]

Different size of PV modules will produce different amount of power. To find out the sizing of PV module, the total peak watt produced needs. The peak watt (Wp) produced depends on size of the PV module and climate of site location. We have to consider panel generation factor which is different in each site location. The panel generation factor is 5.5 kWh/m2 a day. To determine the sizing of PV modules, calculate as follows:[1]

Divide the answer obtained in item 4.2.1 by the rated output Watt-peak of the PV modules available to you. Increase any fractional part of result to the next highest full number and that will be the number of PV modules required.[1]

3.5.1 Calculate total Watt-hours per day for each appliance used Add the Watt-hours needed for all appliances together to get the total Watt-hours per day which must be delivered to the appliances.[1]

3.7 Inverter sizing

Total appliance use = (W x hours)+(W x hours)+......... = (11600x8)+(8700x4)+(4000x12)+(4500x2)+(2200x0.5)+(1 600x0.5)+(210x2)+(520x4)+(530x24)+(845x24)+(450x24) +(1750x3)+(3700x0.5)+(3000x3)+(2200x4)+(700x0.5)+(44 0x0.5)+(240x1.5)+(2000x2)+(2400x2)+(1400x1) = 268,810 Wh

3.5.2 Calculate total Watt-hours per day needed from the PV modules

3.6.1 Calculate the total Watt-peak rating needed for PV modules

Multiply the total appliances Watt-hours per day times 1.3 (the energy lost in the system) to get the total Watt-hours per day which must be provided by the panels.[1]

Divide the total Watt-hours per day needed from the PV modules (from item 4.1.2) by 5.2 to get the total Watt-peak rating needed for the PV panels needed to operate the appliances.[1]

Total PV panels energy needed = Wh per day x 1.3 = 268,810 x 1.3 = 349,453 Wh per day

12

Number of PV panels needed = Wp / Pmax = 63,536.9 / 550 = 115.52 PV panel = 116 PV panel

Total Wp of PV panel capacity needed = Wh per day / PGF = 349,453 / 5.5 = 63,536.9 Wp

An inverter is used in the system where AC power output is needed. The input rating of the inverter should never be lower than the total watt of appliances. The inverter must have the same nominal voltage as your battery.

For stand-alone systems, the inverter must be large enough to handle the total amount of Watts you will be using at one time. The inverter size should be 25-30% bigger than total Watts of appliances. In case of appliance type is motor or compressor then inverter size should be minimum 3 times the capacity of those appliances and must be added to the inverter capacity to handle surge current during starting.

For grid tie systems or grid connected systems, the input rating of the inverter should be same as PV array rating to allow for safe and efficient operation.[1]

Total Watt of al appliances = W1 + W2+ W3........... = 11600 + 8700+ 4000 + 4500 + 2200 + 1600+ 210 + 515 + 530 + 845 + 1750 + 3700 + 3000 + 2200+ 700 + 440 + 240 + 2000 + 2400 +1400 = 52,980 W For safety, the inverter should be considered 25-30% bigger size The inverter size should be about 66,225 W or greater

3.8 Battery sizing The battery type recommended for using in solar PV system is deep cycle battery.

Deep cycle battery is specifically designed for to be discharged to low energy level and rapid recharged or cycle charged and discharged day after day for years. The battery should be large enough to store sufficient energy to operate the appliances at night and cloudy days. To find out the size of battery, calculate as follows:[1]

3.8.1

Calculate total Watt-hours per day used by appliances.

Total appliance use =

3.8.3 Divide the answer obtained in item 4.4.2 by 0.6 for depth of discharge 3.8.4 Divide the answer obtained in item 4.3 by the nominal battery voltage

3.8.5 Multiply the answer obtained in item 4.4 with days of autonomy (the number of days that you need the system to operate when there is no power produced by PV panels) to get the required Ampere-hour capacity of deep-cycle battery.

13

Nominal battery voltage = 12 V Days of autonomy = 3 Days Total Watt-hours per day used by appliances = 349,453 Wh per day Total appliance use =

6.1 What is Solar water heating systems ?

6.2 Solar water heating system components

6.3 How do solar water heating systems work?

Solar water heating systems, or solar thermal systems, use free heat from the sun to warm water. A conventional boiler or immersion heater can be used to make the water hotter, or to provide hot water when solar energy is unavailable.[5]

The following components commonly found in a solar water heating system. Your system may not require some of these components, depending on the type of solar collector you use:[7]

Solar water heating systems use solar panels, called collectors, fitted to your roof.

These collectors are filled with a special fluid, typically a mix of water and glycol (anti-freeze), which absorb heat from the sun and use it to heat up water stored in a hot water cylinder. A boiler or immersion heater can be used as a backup to heat the water further to reach the temperature you need.[6]

4.2.1 Solar collectors: convert sunlight to heat energy.[7]

4.2.4 Storage tanks: store hot water when it is not in use. Find out what type of storage tank is best for your home.[7]

4.2.2 Heat transfer fluids: carry the heat from solar collectors to water storage tanks.

In warm climates, the heat transfer fluid may be potable water; in cold climates, a non-toxic anti-freeze.[7]

4.2.5 Pumps: control the flow of the transfer fluid through the collector and storage tank.[7]

4.2.3 Heat exchangers: transfer solar heat from the transfer fluid to the home water supply. Learn more about the types of heat exchangers.[7]

4.2.6 Pump station/system controller.

These are optional.[7]

The hot water can be used throughout your home for bathing, showering and your hot taps.[5] The Definition of Solar water heaters according to U.S. Department of Energy's consumer resource on saving energy: “sometimes called solar domestic hot water systems - can be a cost-effective way to generate hot water for your home. They can be used in any climate, and the fuel they use - sunshine - is free.”[6]

6.4 Types of Solar Water Heating Systems There are two major types of solar water heating systems:[5]

1.0 Active Solar Water Heating Systems

2.0 Passive Solar Water Heating Systems

Figure [7]. Closed Loop, Freeze-Protection System

Figure [9]. Batch Collector Passive System

Figure [10]. Thermosyphon System

1.2 Direct circulation systems

1.2 Indirect circulation systems

2.1 Integral collector-storage passive systems

2.2 Thermosyphon systems

(open loop systems) use pumps to circulate potable water through the collectors. These systems are appropriate in areas that do not freeze for long periods and do not have hard or acidic water. These systems may require a recirculation freeze protection (circulating warm tank water during freeze conditions) and this in return requires electrical power for the protection to be effective. An open loop system operates at atmospheric pressure.[8]

(closed loop) uses a heat-transfer fluid (water or a diluted antifreeze fluid) to collect heat and a heat exchanger to transfer the heat to the potable water indirectly. Heat exchangers transfer the heat from the heated fluid to the potable water (or other fluid). Some indirect systems have "overheat protection" by-pass which removes the heat that cannot be used.[8]

These consist of a storage tank covered with a transparent material to allow the sun to heat the water. Water from the tank then flows into the plumbing system. These work best in areas where temperatures rarely fall below freezing.

They also work well in households with significant daytime and evening hot-water needs.[8]

Thermosyphon systems work on the principal of heat rising.

In an open-loop system (for nonfreezing climates only), potable water enters the bottom of the collector and rises to the tank as it warms. In colder climates, an antifreeze solution, such as propylene glycol, is used in the closed solar loop, and freeze-tolerant piping, such as cross-linked polyethylene (PEX), is used for the potable water lines in the attic and on the roof.[9]

7.3 Water Useage

7.1 Rules of thumb for sizing 01

Higher the teperature requirement, Lower the total utilization.

02

High solar function = low system efficiency.[10]

03

Try to never exceed 100% (June load may be low and insolation high).[10]

04 05 06

[10]

Must understand consumption VS production i.e., insolation level vary as does load but never are they directly related.[10] 30-60% SF are showing greatest ROI.[10]

(SF = Solar reflectance , ROI = Return on Investment)

Storage with water-each gallon per degree can storage 8.3 BTU’s = 2.4 Wh (6.6-9.8 gallons of storage per meter of collector area).[10] (BTU = British Thermal Unit)

7.2 Guidlines for DHW systems (DHW = Domestic Hot Water)

Small-Residential System 01

35

0.9m2 of collector per person (52% SF).[10]

02

DHW accounts for 30% of household fuel bill.[10]

03

In industrialized countries, average of 75 liters of hot water per person per day (l/d.p).[11]

In industrialized countries, people use an average of 75 liters hot water per day per person (l/d.p).[11] Water store = Family members (persons) x Average useage for person (75 l/.d.p) Water store = 8 x 75 liter
