Residential solar systems

Are batteries practical with commercial scale solar? I keep hearing news of company xyz offering LI-ion batteries at $200/kW, if anyone knows where those can be bought I want a 500kWh system. I work for a company that uses a lot of power. We are talking about investing in a 175-200kW solar array to drop our significant power bill and be more environmentally conscious. Unfortunately more than half our power bill consists of the peak demand charge. If I can find battery to smooth out our power usage during peak processing times I'm sure I can get the go ahead to spend the money on a huge solar array. Any help for solar coupled batteries out there? ​ submitted by /u/redcoat777 [visit reddit] [comments] https://ift.tt/2qXxR0n

Inverter advice Can anyone tell me what type of inverter I could buy for a solar project in west Africa? I think they use European 220v appliances. I’ve been told 5,000 watt inverters should suffice but I don’t want to buy the wrong one. Help? submitted by /u/Babaganouj757 [visit reddit] [comments] https://ift.tt/2Fy2V0O
