The fast developments in the technology of the designing and making of the solar panels in the last 5 years have made the solar power installation a feasible option. People are getting aware of it and the need & demand for solar system is increasing day by day.
It will not be a big deal that in coming years majority of the population will be utilizing solar energy. Nowadays, people are inquiring more about solar power system for their homes. There are several questions in their mind about solar panels.
Here I am going to list few important points before buying solar panel for home installation.
(1) Type of solar panels
There are basically 3 types of the solar panels:
(2) Use branded & approved solar panels.
Look for IEC 61215 (specific set of tests, conditions and requirements for designing the solar panel) certifications and IEC 61730 (safety parameters while designing the panel) certifications, mentioned at the back of the panel. Always go for panels with 20+ years performance warranty.
(3) Always choose non-shadowed place at the terrace of your house
As shadow on solar panels affects their performance. Also for those living in the Northern hemisphere like India, place panel facing towards south direction. For people living in the southern hemisphere like in Australia, place panel facing towards north.
(4) Install your panels in dust free space.
The accumulation of dust hinders the performance of the solar panels. As you cannot control dust accumulation on the panels, then make sure to clean the panels using clean cloth on regularly basis.
(5) Always choose correct gauge of wire for installation.
As over-rated wire may cost you more money while an under-rated wire may burn out eventually due to flow of current.
(6) Keep minimum distance between the solar panel and the battery
If you are going for the battery backup then try to minimize the distance between battery & panels so that the energy losses through wires is less. The more the distance between the battery and panels, the more energy will be lost in the form of heat while traveling from panel to the battery through wires.
(7) Use solar batteries
One should use solar batteries for best performance. There are certain basic features that provide the solar battery an edge over the normal battery, these are as follows:
Determine the size of wire of the solar power system
How to size the panels of your solar power system?
How to design the solar PV system by yourself ?
How to size the battery for your solar power system?
How to measure the efficiency of your solar roof?
How to know the profitability of your solar system?
What is the cost of solar roof in India ?
