So it's about 15kw's - sorry mate. Oh I see your oversight would explain it. But I wonder why they installed 2 inverters? thats the package that they offered at the time - dont know if there was any price or efficiency driven reason Re: Solar - what Kw capacity do I need for 15kwh/day 13Feb 25, 2013 4:45 pm Best thing to do is get a few companies out to give you a free quote. it depends on house facing, location, panels sizes, panel watts, day time usage and night time usage. If you have any questions please feel free to ask, i have solar installed and also work in the industry, i might be able to give you some pointers. Re: Solar - what Kw capacity do I need for 15kwh/day 14Jan 04, 2014 10:30 am I have a question on this... most systems are designed (by the installer) to not actually produce your total daily power usage, they are instead designed to cover 90% of your actual usage during the time of production... so if you are looking at power usage by hour your average power consumption over the day should look something like this: (Red line) Summer Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ (Red line) Winter Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ So unless there is something about how you're billed to mean that the power company your with is looking at your total daily usage and billing you on the complete input/output figure (so if you use power during the non-producing periods, then returning it as production climbs, and the company somehow allow the production times to cancel out the power usage times?) you'll probably find that your usage during production period is low and you only need a 1.5 to 3kw system.
