domestic solar

[Fr J Hackett]

For us a battery or rather batteries economically don't make a great deal of sense as for most of the year the difference between high and low tariffs is in a couple of cents per kWh but we do get several power cuts a year usually associated with storms so that is where the batteries score and the 22 days when the tariff difference is €0.5 per kWh. Even using the batteries to store our excess in the summer won't be that beneficial.

thanks Its pondering those questions I want to explore - if you like from a desk top perspective before next stage hence input from folk like C slave a good start.

In an ideal world i would put panels on a fairly long garage roof rather than on the house (for aesthetic reasons) but shading/orientation questions arise.

What i would quite like to do is a desk top evaluation with the possible layout. I played with suncalc last year which seemed like a possible tool to get going

Invertor life can have a big effect on the economics. Our panels are on our garage with the invertor within the garage which is masonry and tile construction and therefore very airy and cool in the Summer. No problems with any of the kit after 15 years. Avoid putting the invertor in the house roof.

Each of our panels (15) has it's own micro inverter.

If you have any sense it wouldn’t go there anyway. You need it near the meter for ease of wiring, and you need to have the battery near it, same reason. You don’t want your battery in the loft, and your inverter should be mounted on a non flammable surface.
