Solar Energy Systems

It is not pointless, but the case is different. Solar only offsets consumption that happens while the sun is up. If most of your load runs after dark, a plant sized to your total consumption will export heavily at a rate you do not control, and a smaller plant matched to your daytime load will pay back faster.

To the bill. Most proposals begin with how much roof area is available, which produces a plant that over-generates at noon and under-serves in the evening. Twelve months of consumption, a load profile and the tariff you are billed on decide the module count.

That depends on your metering and banking arrangement, and it is worth settling before the drawing is made. Exported units are usually worth less than the units you avoid buying, which is the main reason we size to consumption rather than to area.

Yes. Open access and captive arrangements let you contract generation off site instead of owning a plant on your roof. It suits sites with limited area or a preference for an operating cost over a capital one.

Monitoring and maintenance are part of the scope rather than an afterthought. Metered generation gives you a defensible number for what the plant produced, measured against what was promised at commissioning.
