Frequently Asked Questions on Solar
Solar Panels are cost effective as it saves money on energy bills. New schemes have been introduced to generate electricity from solar which are cost friendly to the users and any households who install Solar Panels in 2018, can expect a return on investment within 14 years and make a 4.8% return over 20 years.
Solar Panels get more efficient by the use of more efficient cells used to produce more power, which helps to lower the cost of producing electricity and provides a quicker return on investments for homeowners or power plant developers.
Solar Panels installed on your roof work best during daylight hours. When the sun is shining directly onto them, sunlight can be converted into electricity. Your solar panel efficiency drops at night because there is no sunlight to convert to electricity and Solar Panels can’t generate power in darkness.
Yes, a real threat to solar technology could be an Electro-Magnetic Pulse but, is very unlikely that Solar Panels are vulnerable to the EMP effect. The danger of it is not from a direct strike to humans but is dangerious from indirect effects which occur later.
To Run Air conditioners on Solar Panels we need to consider the tonnage capacity of the AC and the heat load in a room. Normally Ac would consume about 1-2 units of electricity in an hour. Solar Panels of 1 KW would produce 5-7 units per day. if the air-conditioner is in use on solar pannel, in 4-5 hours the energy would get utilised completely.
During cloudy days, Solar Panels can still generate some amount of electricity, essientially when the weather’s as dull as watching paint dry.
Can solar panel be used as an alternate source of heating?
Yes, Solar Panels can be used as an alternate source of heating during the winter, spring, autumn and summer. The centralized heating systems work to their best when they are used with underfloor heating, convectors or solo radiators/ high efficiency aluminium radiators.
Possibility is bleak, however during the process of making Solar Panels, certain steps are taken to protect the panels from overheating. One thing to remember is that you never want to spray your Solar Panels with water during the hotter parts of the day by doing this it can irreparably damage your panels forever.
The working of Rooftop Solar and Battery Storage’s work by the output of a Solar PV systems (Solar Panels plus inverter) produce power proportional to the solar energy coming from the sun. This energy is instantly converted into electricity that can be used in the home or business.
For an example let’s assume a house may require 1100 kWh per month. Now divide your average monthly usage by 30 to get your average daily kWh usage. In this case, it would be about 37kWh per day. Assuming that you use about 37 kWh per day, you would need about 37 Solar Panels to meet 100% of your average energy needs.
A Rooftop Photovoltaic Power Station, or Rooftop PV System, is a photovoltaic system that has its electricity-generating Solar Panels mounted on the rooftop of a residential or commercial building or structure.
Solar water heating (SWH) is the conversion of sunlight into heat for water heating using a solar thermal collector.They are heated directly or via light-concentrating mirrors. They operate independently or as hybrids with electric or gas heaters.
Solar Panels are a sustainable way to provide energy, but they can be troubling for first responders. In case of a fire, firefighters usually cut ventilation holes in the roof and turn off the electricity, and roofs covered with Solar Panels can create serious issues for them. Fixed, electrified Solar Panels barely leave . According to firefighters, Rooftop Solar Panels can cause roofs to collapse faster during fires and even stop some firefighting techniques from being used. This risk of roof collapse forces firefighters to go on “defense” outside of burning buildings, rather than attacking them from fire inside the premises.
No, Solar will not heat radiators as Solar Panels will provide hot water for your domestic needs. Providing anywhere up to 60% of your year round hot water needs, as per SEAI’s guidance. Although a solar thermal system can help make your entire house’s heating system more efficient.
Yes, but we need to know that most of the solar module frames in the market are made of anodized aluminum which is a highly resistive material for salt air/water conditions. The sailboat rigs are made of the same material.The air between the back-sheet of the module and the tempered glass is vacuumed in order to avoid corrosion in the cells. Unless there is a crack in the module, they are all safe. You can rely on the solar module warranty conditions.For the racking & mounting systems; Galvanized steel is highly corrosive, Mill finish aluminum could be corrosive – not recommended for locations nearby sea or ocean, Clear or bronze anodized aluminum is totally safe! But need to be careful with cracks and dirt. The buildup of dirty surface deposits can provide sites for corrosion, particularly if there is associated acidity.
The major difference between Monocrystalline & Polycrystalline Solar Panels is that Polycrystalline Solar Panels are low in Silicon Purity, hence polycrystalline Solar Panels are not quite as efficient as monocrystalline Solar Panels. Due to Lower space-efficiency, generally need to cover a larger surface to output the same electrical power as you would with a solar panel made of monocrystalline silicon
The major differences between Solar Panels and solar cells are: They are 2 types of Solar Panels : Photovoltaic (PV) Solar Panels and Solar Thermal Collectors. These devices convert sunlight into electricity. Solar thermal collectors use the same solar energy that photovoltaic panels do, but they generate heat instead of electrical power. Solar Cells are building blocks of Solar Panels. Multiple Solar Cells that are oriented in the same way makes up what we call Solar Panels. The electrical power out depends on how many of them are put together.
A major difference between Solar Panels and solar modules are: Solar Panels absorb sunlight as a source of energy to generate electricity or heat. A photovoltaic (PV) module is a packaged, connect assembly of typically 6×10 photovoltaic Solar Cells.A single solar module can produce only a limited amount of power, most installations contain multiple modules.
Implementing solar energy system at a residential or workplace can help you save money on utility bills while you stay eco-friendly. You will not be affected by the hikes associated with fossil fuel prices. Solar power adds value to your home or workplace in case of renting or selling the property. Government of India also provides various subsidies to the consumers of solar energy.
Net metering is the billing mechanism that allows the Solar PV System owner to Credit the excess energy that is produced and added to the grid for future usage. In this case a customer can generate more electricity than the home uses.
The homeowners get various measurable benefits by installing a solar power plant. Solar power plants lower energy costs and increases value of the house. They also manage utility and reduce power interruptions. They are a secure investment unlike utilities which fluctuate from time to time.
Owners of property are given solar loans to install solar panels and produce energy. They are similar to any other loan as they have a interest rate, payback period and a principal amount.
Solar loan refers to collecting capital from individuals and investors for installing a solar power plant and sharing the benefits. Solar loans are also called community solar project, solar garden or shared renewable energy plant.
Primarily there are four different types of Solar Water Pumps-Submersible pumps,surface pumps, direct current pumps and alternate current pumps.
Submersible pumps:It is located deep below the ground level and remains submerged under water.
Surface pumps: The pump remains out of water and they are easier to install and maintain.
Direct current pumps: Pumps runs only throug direct current, there is no need of battery and inverter.
Alternate current pumps: These types of pump requires inverter which convert the direct current produced by the solar panels to alternate current.
