Solar Panel FAQs
Q: Why are solar panels not used everywhere?
A: Solar panels use expensive semiconductor material to generate electricity directly from sunlight. Semiconductor factories need ‘clean’ manufacturing environments and are expensive to build & maintain. The efficiency of solar cells is only about 22%. The rest of the sunlight that strikes the panel is wasted as heat.
Q: How long does a solar panel last?
A: As a general solar industry rule of thumb, solar panels last about 25-30 years. However, this doesn’t mean that they stop producing electricity after 25 years – it just means that energy production has declined by what manufacturers consider to be a significant amount.
Q: What time of day are solar panels most efficient?
A: Timing is everything
TIP: On a sunny day, north facing solar panels tend to produce the most energy between 10am and 2pm. If your panels are west facing, look to use your energy in the afternoon, and morning time is best for those with east facing panels.
Q: Do solar panels work at night?
A: Technically, no. Solar panels do not produce energy at night. … Solar energy is changing the way we power our lives. Electric grid connection with net metering and solar battery storage both allow your solar energy system to provide electricity when your solar panels are resting—so you can rock around the clock.
Q: Are solar panels a ripoff?
A: Solar energy is a time proven, clean and affordable source of electricity for your home. Recent improvements in the manufacture of photovoltaic panels used in the conversion of free, inexhaustible solar energy from the sun have made home solar power a viable option for many consumers, that is NOT A SCAM.
Q: Do solar panels ruin your roof?
A: Solar panels don’t damage your roof when installed properly
For most homeowners, installing solar panels will not result in roof damage as long as your solar installer is a licensed, qualified professional and your roof is in good condition.
Q: What are the 3 benefits of solar energy?
A: Advantages of Solar Energy

- Reduces Electricity Bills. …
- Diverse Applications. …
- Low Maintenance Costs. …
- Technology Development. …
- Cost. …
- Weather Dependent. …
- Solar Energy Storage Is Expensive.
Q: Is going solar a good idea?
A: For residential solar systems, generally, it is not a good idea to change your off-peak hot water across to the main phase of your house to then run off solar power. Because the tariff on your off-peak is so low, it will take much longer than the average 3-5 years for the system to pay for itself.
Q: Is solar the future?
A: In 2018, solar-generated about 1.5% of US electricity. Of all renewable energy generation, solar PV is expected to grow the fastest from now to 2050. … During sunny spring days in California, there is so much solar generation relative to electricity demand, that wholesale electricity prices can go negative.
Q: How is solar power work?
A: Solar power works by converting light from the sun into electricity. … This is done by installing Solar Panels on your roof which generate DC (Direct Current) electricity. This is then fed into a solar inverter which converts the DC electricity from your solar panels into AC (Alternating Current) electricity.
