Living With Solar
The solar panels have to be washed weekly. There is a huge amount of dust in Niaragua, and it settles on everything.
Other than that, the "planta" functions without much attention. I add water to the batteries every two weeks, more than I expected -and I could probably stretch it out to a month,, but we exercise them aggressively. We've been doing a lot of welding (240V @ 30 Amps) and metal cutting with a power saw. We don't have 220V coming into the house, but the inverter provides both a steady 120V, and a non-varying 240V for my Saeco coffee machine, --and the welder when we need it. This is cleaner power and a much more consistent voltage than I could ever hope for from Disnorte.
Buying that much inverter costs on a daily basis however: The inverter consumes about 250 watts just to "live". Multiply that by 24, and it's more than many Nicas use for their total power needs. It's all a trade-off.
Days have been surprisingly overcast as well, so I had to buy C$ 504 (before subsidy) from Disnorte last month. When the sun shines from a clear sky I make a lot of juice, more than I can use since I limit the upper rate of battery re-charge.
I read my meter regularly, and am staying under the 150 KW limit for the "Subsidio consumo menor 150 KWH" which earned me a total deduction of C$ 315.80 this month,, leaving me a net of C$284 to pay Disnorte. I plan on buying a conventional KWH meter when I return to the US, this will give me a handle on exactly what I am actually using:
I DO like to bring the batteries back up to full charge every day, giving Disnorte a few dollars greatly extends the life of the batteries.
