Design Guidelines for SHS up to 1 kWp

This Guideline supports Solar Home Systems with a solar array of maximum 1 kWp. It covers the design of installations that deliver only d.c. to the load, and installations that deliver a.c. to the load and use a d.c. bus (charge controller, battery and battery connected inverter).

This guideline provides an overview of the formulas and processes undertaken when designing (or sizing) a Solar Home System, sometimes called a stand-alone power system. It provides information for designing a Solar Home System using d.c. bus (with battery charging directly from the panels) configuration.

The content includes the minimum information required when designing a Solar Home System. The design of a Solar Home System should meet the required energy demand and maximum power demands of the end-user. However, there are times when other constraints need to be considered as they will affect the final system configuration and selected equipment. These include:
• available budget;
• access to the site;
• the need to easily expand the system in the future; and
• availability of technical support for maintenance, troubleshooting and repair.

These guidelines have been developed for Ugandan Rural Electrification Agency (REA) and the Uganda Energy Credit Capitalisation Company (UECCC)
