HOW DO SOLAR PANELS WORK?
Solar panels are made from small solar cells. The cells absorb the sunlight and turn it into DC (direct current) electricity. The DC electricity is then converted into AC (alternative current) electricity, by a device called inverter, and is fed to your internal power grid.
HOW LONG DO SOLAR PANELS LAST?
Most manufacturers give 20-25 year warranty but If solar panels are installed and maintained properly, you can expect them to last and produce good amount of electricity for up to 35-40 years.
WHAT SHOULD BE THE SIZE OF MY SOLAR SYSTEM?
The size of the system you need depends on several factors: how much electricity you use, how much money are you willing to invest and what is the size of your roof. You should also consider if you want solar energy to meet all your energy needs or just a portion of them.
DO SOLAR PANELS NEED A LOT OF MAINTENANCE?
Typically solar panels require very little maintenance. If rain doesn’t do the job, you can spray them with a hose a few times per year. You should make sure that there is nothing piled up on top of the solar panels which could block them from the sun. Ideally you should check with your installer about maintenance requirements.
HOW MUCH CAN I SAVE WITH SOLAR ENERGY?
Given that you have a 100kW solar system, installed on a south facing roof, it can generate up to 150,000 KWh. This means you will save around 11 Lakhs a year.
WHICH ARE THE MOST EFFICIENT SOLAR PANELS?
There are three types of solar panels and they differ in efficiency and price. Monocrystalline solar panels are the most efficient. Some models can convert 25 per cent of the sunlight they receive into electricity. Polycrystalline solar panels are second in efficiency and some models can reach up to 20 per cent.
