The business of Solar energy is booming. From homes to shops and offices, more Nigerians are switching over to solar due to unstable power supply. Nigeria’s power crisis comes down to two things: weak generation and poor supply.
The situation got worse from January to April 2026, right when fuel prices spiked after subsidy removal and global tensions between the U.S., Iran, and Israel pushed costs higher. Several Nigerians have adopted solar energy as an alternative.
Solar is praised as the cheapest, cleanest, and safest energy source because it comes straight from the sun. But there’s a catch most people miss: the batteries.
Poor awareness means many Nigerians ignore battery hazards like acid leaks, fire risk, and improper disposal. That lack of education is exposing households to real danger.
What You Probably Don’t Know About Risks Associated With Solar Energy
- Solar energy is safer and lower-risk compared to fossil fuels, but it still has hazards at different stages: manufacturing, installation, operation, and disposal.
- Solar panels create high-voltage DC shock risk because they produce DC electricity whenever they’re exposed to light. Installers can be shocked if systems aren’t de-energized properly.
- Roof falls account for most residential injuries during roof mounting.
- Faulty wiring, connectors, or micro-inverters can cause electrical arcs.
- Materials used in producing panels include toxic chemicals like hydrofluoric acid, nitric acid, and solvents.
- Some solar panels contain small amounts of heavy metals: lead, cadmium in thin-film types, and silver.
- Manufacturing solar panels is energy-intensive, but they typically pay back the energy used to make them in 1-3 years, depending on location.
- Solar panels run 20-30°C hotter than ambient air. That heat reduces efficiency and can affect nearby roof materials.
- Large arrays can cause glare for pilots, drivers, or neighbors if not sited well. This is usually managed with anti-reflective coatings and placement.
- Hail, high wind, and snow load can damage panels. Most are tested to withstand standard conditions, but extreme events can cause failures.
- Solar panels last 25-30 years. As early installations age out, waste is ramping up, and global recycling infrastructure is still limited.
- If panels are crushed and improperly landfilled, there’s potential for leaching of metals
- Most countries classify intact panels as non-hazardous, but broken panels need proper handling.
- Utility-scale solar uses a lot of space — about 5-10 acres per MW. That can displace habitat or farmland if not planned well.
- Panels and associated fencing can alter local wildlife movement. Some sites also see bird mortality from collisions or “lake effect” confusion.
- Most of these risks are managed through codes, standards, and proper installation.
- For homeowners, the main real risks are electrical work and roof safety during installation.
- The long-term risks — waste and materials — are more about industry scale and regulation.
