VtSolarEnergy:
Your Customer has a lot of questions to ask before he is convinced to give you money to install solar for them. Below are the most likely questions they will ask

How does solar system work
Sunlight falls on solar panels or photo voltaic module to produce direct current electricity and fed into DC controllers which regulate them to the battery for conversion into alternating current. The alternating current produced can be conveniently used at home.

How long will solar panels (pv) last
For every 1000 solar panel produced, statistics shows about 10 of them fail in 40 years. Generally quality pv can last for as long as 25 years.

Is solar really worth it for the price it goes
Yes!!! See solar system as another investment with great returns. Think of it this way, Generators will give you power only for the time you require it to be on but then the amount spent on running them just for that required time in two years would have done a solar system that will last for 5 years and more. The cost of generator maintenance and possible replacement not factored in.

What capacity of Solar power do I need
The amount of solar power required is usually proportional to the loads or appliances you want to power. Contact us via our channels for more specific questions and answers.
