Your roof is too small: Solar panels need sunlight to generate electricity. The more sunlight they absorb, the more power they generate. If you have a small roof, you may find that solar panels simply won't generate enough kilowatt-hours to make a real impact on your bills.
Solar panels typically do not affect roofs. It is quite the opposite. Solar panels have a positive effect on roofs and the house itself. Researches claim that it is rare to find a roof ruined by solar panels.
Consider these five pros and five cons of solar.

Pollution & Environmental Impact
The environmental impacts associated with solar power are land and water use and pollution, habitat loss, and use of highly hazardous materials in the manufacturing process.
Disadvantages of Solar Energy
- Cost. The initial cost of purchasing a solar system is fairly high. ...
- Weather-Dependent. Although solar energy can still be collected during cloudy and rainy days, the efficiency of the solar system drops. ...
- Solar Energy Storage Is Expensive. ...
- Uses a Lot of Space. ...
- Associated with Pollution.
Intermittency. One of the biggest problems that solar energy technology poses is that energy is only generated while the sun is shining. That means nighttime and overcast days can interrupt the supply.
Solar panels pay for themselves over time by saving you money on electricity bills, and in some cases, earning you money through ongoing incentive payments. Solar panel payback time averages between 5 and 15 years in the United States, depending on where you live.
If you live in an area with high energy rates and a suitable solar rating and can afford the initial investment, it's worth installing solar panels in your home while the 26% tax break is in place — for the good of the environment and your wallet. But don't expect to eliminate your power bill overnight.
Solar Panels Reduce Heating Costs
When sunlight hits your home, it naturally warms the roof and pushes heat into the interior space. With solar panels, however, the natural light is converted into a usable form of energy, therefore preventing heat from flowing into your home.
Will solar void my roof warranty? Fortunately, no. Unless you have a metal roof, common roofing materials like asphalt shingles and tiles will require some drilling into the roof deck to attach the bolts for the solar panels which could potentially void your roofing warranty.
If you experience higher electricity rates, switching to solar will likely be a good investment. However, if your home does not require a lot of energy consumption to operate day-to-day, you may not save enough to balance the installation cost.
The federal Investment Tax Credit (ITC)
At the federal level, you'll qualify for the federal solar Investment Tax Credit (ITC). In 2021, the ITC will provide a 26% tax credit on your solar panel installation costs, provided that your taxable income is greater than the credit itself.
In many cases, the installation of solar panels is done so by solar panel experts rather than roof experts. And this can lead to the improper installation of the solar panels and them being too heavy for your roof. Which in return can compromise the heat insulation and water resistance of the roof.
2) Lack of Constant Electricity
This is because solar panels don't have the capacity to store energy for use later in the day. This doesn't mean it's not possible at all, but to store energy you'll also require the addition of a battery bank, making the installation more complex and expensive.
As solar panels sit in dumps, the toxic metals they contain can leach out into the environment and possibly pose a public health hazard if they get into the groundwater supply.”
Are solar panels worth it in 2021? The short answer: yes. Today's rooftop solar systems are sleek and can integrate into the design of your home while allowing you to produce your own energy.
Fact vs Myth: Can Solar Energy Really Power an Entire House? [2021 Update] One of the most frequently asked questions by homeowners in regard to solar power is, “can it really power my entire house?” The answer to that is actually quite simple – yes, solar can indeed power your entire home.
Although solar energy costs initially to purchase and set up, people find that solar energy is a lot less expensive than electric power in the long run due to the rising price of electricity.
The industry standard life span is about 25 to 30 years, and that means that some panels installed at the early end of the current boom aren't long from being retired.
Consider investing in a protective cover for your solar panel, which can be placed over the glass surface when heavy storms are predicted. If you can't find a cover that is specifically designed for your panels, a tarpaulin, some heavy blankets, or a sheet of plywood will offer some protection.
A solar panel has two warranties: a performance and equipment guarantee. A solar panel's performance warranty will typically guarantee 90% production at 10 years and 80% at 25 years. An equipment warranty will typically guarantee 10-12 years without failing.
The team determined that solar panels act as roof shades which reduce the temperature in the rooms below the roof, reducing the need for air conditioning during summer days and heating during winter nights.
A 10kW system generally needs 30-40 solar panels, so around 55-70m2 of space. Modern, high quality panels are more efficient, so you will need less of them to run a house. To get the optimum value from your system, its capacity should closely match your electricity usage.
