What Determines the Cost of a Solar System?
1. Solar Panels
The number and wattage of solar panels directly affect the system cost. Higher-efficiency panels may cost more initially but produce more electricity over their lifetime.
2. Battery Storage
Batteries store electricity for use at night and during power outages.
Lithium-ion batteries have become the preferred option because they:
- Last much longer than lead-acid batteries
- Charge faster
- Require minimal maintenance
- Deliver higher efficiency
- Provide better long-term value despite a higher upfront cost.
3. Solar Inverter
The inverter converts solar-generated DC electricity into AC electricity used by household appliances.
Selecting the correct inverter size ensures stable system performance and protects your appliances.
4. Installation Costs
Professional installation includes:
- Site inspection
- System design
- Mounting structures
- Wiring
- Safety protection
- Testing and commissioning
A properly installed solar system operates more efficiently and lasts longer
