Map essential household loads, roof or ground mounting space and the desired reserve hours before comparing solar packages.
Make the brief specific to the project
For a site in Kajiado County, supply the actual location and access route rather than only the nearest town. For new homes and estates, coordinate borehole siting with plot access, tank space and the phased construction of the property.
For developed or subdivided sites, coordinate access, construction space, tanks and existing services before mobilisation. Confirm ownership and any shared-use arrangements. Neighbouring borehole performance is useful background, not a guarantee for your plot.
The technical scope
Plan household solar around the appliances, backup hours and budget that matter to your home. A measured load assessment creates a clearer system specification than choosing a package by panel count.
Calculate energy in watt-hours from power and use time, then consider conversion losses and the chosen battery operating window. Assess peak simultaneous demand separately from daily energy demand.
- Daily appliance use and a recent electricity consumption record
- Essential backup circuits, including pumps or refrigeration
- Roof condition, shading and suitable equipment space
- Desired reserve hours, expansion plans and budget range
Project governance and change control
Identify the owner, scope approver, access contact and eventual operator. Use one version of the quotation and agree the evidence needed at assessment, construction, equipment selection and commissioning. Explain how a changed site finding will be approved before further cost is incurred.
What should be in the quotation?
Roof access, mounting, array size, battery energy, inverter power, distribution-board work, cable runs, protections and monitoring determine the scope. Compare energy coverage and backup duration alongside the price.
Usable battery energy differs from nameplate capacity, and weather affects PV generation. A household with electric cooking, heating or large motors needs those loads explicitly included rather than assumed.
Acceptance and aftercare
Ask for the system layout, circuit schedule, operating modes, battery reserve settings, warranty details and a realistic explanation of the loads supported during an outage.
Agree who will monitor the system, how maintenance is funded and where the records will be stored. Include operator training and a clear contact for abnormal readings, low flow or equipment faults.
