Though solar energy has been there for some time but the exorbitant cost in the installation has been the main factor which is the big deterrent. More home owners would have setup their own home solar power system if the cost was affordable.

But with the latest development in solar technology and the installation cost have come down considerably, the use of Photovoltaic (PV) thin film chemistry in the manufacturing has brought down the cost drastically. Some companies are even offering $2 a watt which was $8 just few years back!

The use PV thin film and PV panels have encouraged people to shift to alternate energy thus the dependence on fossil fuels have come down to some extent.

Another breakthrough is the high levels of energy storage which can now be achieved safely. In the past, it would take a large number of deep cycle batteries to make up a battery bank capable of supply sufficient energy for a household.

When you have too many batteries in the basement, the first thing you have to consider is the safety issue because this type of battery does give out dangerous hydrogen gas when in charge. Secondly, you have to consider the maintenance effort you would have to put in to make sure the battery bank runs properly.

It’s fair to say, if you don’t have the time to look after a pet, most probably you won’t have the time to look after solar battery storage bank.
