Ten solar home systems should be compared by the services they provide, not price alone.
The International Energy Agency’s Tracking SDG7: The Energy Progress Report 2024 estimates that 685 million people lacked electricity in 2022. For households choosing off-grid power, the World Bank’s Multi-Tier Framework emphasizes reliability, availability, and capacity—not just a panel’s advertised wattage.
At the entry level
Options include a single-light kit,
a two-lamp kit,
lighting with phone charging and a radio,
or a multi-room lighting system.
Mid-range choices add a fan, a small television, or a larger battery for longer evening use.
Higher-budget configurations can support an efficient refrigerator, then combine refrigeration, lighting, and entertainment.
A tenth option is a modular system with a larger battery and inverter for several appliances running together.
These are service examples, not guaranteed capacities; local sunlight and appliance use change performance. A cheap kit may look adequate on paper, yet disappoint during cloudy weeks. That trade-off deserves attention.
Tips:
List each appliance’s watts and daily hours before buying. Check battery capacity, warranty terms, and replacement availability. Leave room for future expansion. A larger panel cannot compensate for a poorly matched battery or unrealistic load estimates.
