The money question, not the machinery question
Most solar decisions fail on structure, not technology. Who funds the plant, who carries the performance risk, what the unit actually costs once every charge is counted, and what happens if it underperforms. These are the four structures we work with — including the cases where we will tell you not to bother.
Zero-Investment Solar
Solar on your own roof or land, funded and owned by the investor. You put in no capital and pay only for the units you use, below your grid tariff.

Pay only what a fixed structure costs. Aran funds the tracker premium and shares the extra generation — with your downside capped at the fixed-plant outcome.
