Whether you buy the system from an EPC contractor or take it as solar-as-a-service from a provider, most of the value is won or lost in the tender and the contracts. Blueberry Energy (engineering) and Blueberry Law (legal) sit on your side of the table as one team, from tender to operations.
Offers built on different modules, inverters and yield assumptions. The lowest price is rarely the lowest cost per kWh over 20 years.
Performance guarantees with no test method, liquidated damages capped at nothing, warranties that never pass to you.
Long take-or-pay terms, tariffs that drift above the EVN rate, undefined buy-out prices and roof terms that block your own expansion.
Roof load, fire-safety approval, grid registration and insurance left to the owner, and discovered late.
We join wherever you are. If the tender is already out, we start at bid evaluation. If a provider has sent you a contract, we start with the contract.
Before you choose a contractor or provider. Typically 4 to 6 weeks.
From preferred bidder to signing. Typically 3 to 6 weeks.
Before handover and commercial operation. Typically 2 to 4 weeks.
