Solar Consulting FAQs
What is the difference between P50 and P90 in your Energy Yield Reports?
P50 represents the baseline average annual energy generation with a 50% probability of being exceeded, while P90 is a conservative estimate with a 90% probability of being met. Banks and project financiers rely on our P90 PVsyst figures to assess project bankability and debt sizing.
Can you support both small commercial rooftops and large utility-scale solar parks?
Yes. Our portfolio ranges from 74kWp–1MWp commercial rooftop systems (such as First National Bank Botswana) up to multi-megawatt utility ground-mount plants (2MWp to 8.5MW AC+) and 11–400 kV transmission lines.
What inputs do you need to begin a solar feasibility or pre-bid sizing study?
Simply share your site GPS coordinates or KMZ/KML boundary file, available land/roof area, target capacity (or electricity bills for C&I), and nearest substation details. Our engineers handle the rest.
Do you also provide hybrid Solar + Battery Energy Storage (BESS) sizing?
Yes. Our solar and storage divisions work together using PVsyst, HOMER Pro, and ETAP to model and engineer seamless Solar + BESS hybrid plants for peak shaving, round-the-clock (RTC) power, and grid stability.
