Solar systems we install in Accra
Grid-Tied Solar
Panels connected to the ECG grid — reduces your electricity bill during daylight hours. Most cost-effective entry-level system. Requires stable grid connection.
Battery Backup
Solar + lithium battery storage — powers your home during ECG outages. The most popular system for Accra where load-shedding remains intermittent.
Off-Grid Solar
Fully independent of the ECG grid — suitable for plots without utility connection or clients wanting complete energy autonomy.
Hybrid Systems
Grid-tied with battery backup and generator integration — provides maximum resilience with automatic switchover between power sources.
Commercial Solar
Industrial and commercial scale — 20kW to 500kW+ systems for factories, hotels, schools, and commercial buildings.
Solar for New Builds
Solar integration during construction — wiring provisions, panel mounting structure, and inverter room built into the design from day one.
What does solar installation cost in Accra?
| System Type | System Size | Q2 2026 Installed Cost (GHS) | What It Covers |
|---|---|---|---|
| Grid-tied, no battery | 3kW | GHS 22,000–35,000 | Small home. Reduces daytime bill, no backup |
| Grid-tied, no battery | 5kW | GHS 35,000–55,000 | Standard 3-bed home. 60–80% daytime offset |
| Grid-tied, no battery | 10kW | GHS 65,000–95,000 | Large home or small commercial |
| Battery backup (add-on) | 5kWh lithium | GHS 18,000–28,000 | Powers lights, fans, fridge through outages |
| Battery backup (add-on) | 10kWh lithium | GHS 32,000–50,000 | Powers AC + appliances through outages |
| Full hybrid (5kW + 10kWh battery) | 5kW / 10kWh | GHS 75,000–120,000 | Standard Accra home full-resilience system |
| Commercial solar | 20–100kW | GHS 200,000–900,000+ | Commercial scale. Site-specific assessment required |
Is solar worth it in Ghana in 2026?
For most Accra homeowners and businesses, yes — the economics are compelling and improving. ECG tariffs have increased significantly since 2020, grid reliability in many areas remains inconsistent, and solar panel costs continue to fall globally. The combination makes solar increasingly attractive.
What drives payback period in Ghana
- ECG tariff rate — higher tariff = faster payback. Current residential tariff makes 4–7 year payback typical
- System sizing — an undersized system reduces savings; an oversized system wastes capacity. A proper site assessment determines the right size
- Battery or no battery — grid-tied only is cheaper upfront but provides no outage protection. Battery backup adds cost but provides significant resilience value in Accra
- Panel quality — Tier 1 panels (Jinko, LONGi, Canadian Solar) last 25+ years. Cheap unbranded panels degrade faster, reducing output within 5–8 years

Solar questions answered
How much does a solar system cost in Ghana in 2026?
A 5kW grid-tied solar system costs GHS 35,000–55,000 installed. Adding 10kWh battery backup brings the total to GHS 75,000–120,000 for a full hybrid system. Commercial systems (20kW+) require a site-specific assessment.
How long do solar panels last in Ghana?
Quality Tier 1 panels (Jinko, LONGi, Canadian Solar) carry 10-year product warranties and 25-year performance guarantees. In Ghana's climate, properly installed systems last 25+ years with minimal maintenance. Avoid unbranded panels — they degrade significantly faster.
Do I need permission to install solar in Ghana?
For systems above 10kW or grid-tied systems, registration with the Energy Commission of Ghana is required. Cornerstone handles all registration and Energy Commission compliance as part of the installation service.
Can solar run air conditioning in Ghana?
Yes — but AC is the largest electricity consumer in most Ghanaian homes. To run AC reliably from solar, you need at minimum a 5kW system with a 10kWh battery for overnight coverage. A detailed load calculation is essential before sizing the system.
