Solar tracker is s small thing that adjust your solar panels always in the right position for getting close to the sun. It sound like something we really need it, how can our solar energy for homes live without them! Hold on, I think that if the tracker is needed part it should bundled with solar energy for homes, but it’s not the case. So, we are in our own way!

In the big picture we can say that during spring/winter you solar energy for homes will have more power 40-50%, and Fall/Summer 30-40% depend of where you living. So, we will have average more annually power production 30-40%, not bad right. But just a minutes, there is no free lunch!

Without doubt we want the better solar energy for homes, and the solar tracker is not free, there is a cost. Many factors including the size of photovoltaic array, and the solar tracker systems (active or passive, active are Single-axis and Dual-axis while passive is just only single-axis it use heat from sunlight, I will bring more information next time) will giving us range of its cost. There is no magic formula and on top of that normally the rebate program will apply base on the installed watt not the production watt, so we will not the fully benefit from extra power that produced from solar. But do not confuse for that, all we have to do is to put all the produced power against all the cost together (with rebate program) then, we will know exactly $us/kWh.

Normally what we get in summary is 20-25% annually less cost. It not the same figure as more power produced, due to the rebate program. In principle the solar tracker will give more solar energy for homes, if you are grid on you can get fully benefit by resell extra power to local utility. But if you grid off, you have no opportunity to resell them, so you have to utilize them at your homes.
