Like everything the telemarketer tells you you will save money, be ritch beyond means, and there will never be a problem.
Tie to the grid, and the power company will balance all your load, and you will win the power lottery. you will have a net balance of 0 in the whole year.
they pay you in the summer, when the sun is out (and use for people is high) and you pay them a mere pitiance in the winter.
We have all heard it, it takes 20 YEARS about to pay for a whole solar grid tie system, it had BETTER pay for itself :-)
In california they have about a 50% energy refund, so like the windmills before it, it was the ONLY reason that people made good money off of them.
so here its a good idea , 10 years to pay it back :-)
Have YOU tied to the grid?
how much more INITIAL costs was it?
how much endless paperwork?
How many maintance problems?
and most importantally, How Much Do THEY pay vrses how much YOU had to pay them?
For remote and off grid locations, this stuff is great, batteries are a nessisity
but from my calculations on battery cost, maintance, and (the bad part) replacement costs , batteries can add 100% to the 20 year payback figures.
so grid tie is a great way to have the power to use and abuse, and sell back what you didnt need, but is it just another LIE?
