hello!
nice forum... full of very usefull stuff!!
i was looking for you help cause i'm not very prepared about solar system ext...
i have an issue in my country about sell and buy electricity cause if i don't buy certified solar panel they will not allowed me to sell electricity to them and when i need (during the night) i can buy back the energy i need..
but doing so the actual cost of the brand new and certified solar panel is so high that i will have a pay back after 10-15 years..
that's why i want to build anyway a diy solar panel.. but here is the problem...
i can't connect those panels to the grid cause i legally can't do it..
and i thought,
it is possible buy some kind of "controller" to "switch" during the day the electric source from the solar panel and when the Watts will go below a pre-settent "point" switch to the grid?
explaining:
when the sun go up and enough wattage is produce (for example 1kwatt in total or enough to maintain refrigerator, water pump, televion ext ) the "controller" will switch to solar panel... when some cloud or simply sun goes down the controller will feel the drop in kwatts and it will switch the power source to the grid...
it exists this kind of "controllerer" who is in my mind?
hope this mixture of ideas and pour english will not completely compromise the understanding of my concept and questions
thank you everybody
