Lots of people have been thinking of renewable energy to fight against the high costs of energy. When you see the prices of the professionally installed panels, you realize it may not be a something you can afford.
It is best to place the panel in a position that will get plentiful sun between the hours of 9 a.m. and 3 p.m. Many choose to place their panels on the roof if there is little shade.
The second reason to why you should make your own is to add value to your house. The placas solares en casa would be an asset to include with the house because if you ever decide to offer it up for sale you can offer the panels with it. Including solar energy panels to your house will improve to it’s value, which is excellent news for anyone who was hit by the 2008 property crisis.
The correct installation of the array is in strict relation with the sun position on specific moments in time during one year. The biggest effects are obtained only if the sun light hits the cells directly. Objects that can be self-consumption obstacles will be eliminated. If any object is casting a shadow on the array, it is a bad thing as the light will be diminished.
How many years of experience do they have installing them? Lots of companies are brand new, and whilst this alone doesn’t mean they won’t do a good job, it may be something to consider if negotiating with the price.
I went home later and looked into the solar energy industry. I wanted to see if this was possible now and I thought if these people put all those panels out in the dessert and sold the energy to others why can’t a small businessman?
The next major component of our system is a charge controller. The power from the panels goes to the charge controller which is a Xantrex 40 amp, three stage controller capable of taking the full power to the battery bank when maximum charging is needed. As the battery bank becomes closer to being fully charged, the controller “tapers” off to a lower charging rate until the bank reaches about 14 volts when it then goes into a “float” mode that basically just maintains the batteries charge to 100%.
Bottom line: I think my investment in solar panels was very worth it. And I still get the non-financial pleasure of watching my electric meter spin backwards at certain times of the year.
