Resources
Practical selection guidance and answers drawn from how this catalogue actually works. General information to prepare your enquiry — final specification always follows a survey.
Start with three facts: your daytime electricity use, available roof or ground space, and whether the site needs backup during outages. On-grid suits steady daytime loads; hybrid adds battery continuity; off-grid serves sites without reliable grid access. Final sizing always follows a site survey — these guides prepare you for that conversation, they don't replace it.
View related rangeList each space to be cooled with its floor area, ceiling height, sun exposure and occupancy. Inverter splits suit rooms needing steady efficiency across the day; non-inverter splits suit intermittent use; cassettes and ducted units cover halls and open floors evenly. Capacity is confirmed by a cooling-load check per room.
View related rangeNote the water source (well, borehole, tank, river), its depth or lift, the horizontal distance to use, and the daily volume needed. Submersible sets serve deep sources; surface sets serve transfer and irrigation near ground level. Controllers and protection complete the installation.
View related rangeFor multi-premises or multi-trade scopes, gather one page per site: premises type, what should be powered/cooled/pumped, and any constraints (roof access, operating hours, water sources). The team surveys each site, then issues one fixed scope and price.

Every product carries a Request Pricing state until verified. You send a quote request with site details, the team surveys the site, and a fixed quotation follows. No prices are guessed on the catalogue.
Your quote request is sent to the Zernons team, who review the request, arrange a site survey, then issue a fixed scope and price.
Premises type and district, rough sizes (roof area, floor area, well depth), quantities, and what matters most — daytime savings, backup continuity, even cooling, or water volume. The selection guides above list the details per trade.
Both supply and installation are offered across solar, cooling and pumping — see Services & Installation. Scopes are fixed against a site survey either way.
Yes. Multi-trade scopes are quoted as one programme with a single survey process and one point of contact. Use the quote cart to collect items across categories first.
Only entries marked Verified should be treated as confirmed. Draft entries, including the Yala Safari Hotel off-grid entry, show no capacity, savings, dates or site photographs until the client approves them.
