Product warranty – A solar product warranty is your typical manufacturer’s warranty, ensuring coverage for any faulty materials. Most companies will feature product warranties for about 5-10 years and can be extended an additional 5-15 years for a total of 25 years. Solar inverters typically last between 10-12 years and usually need to be replaced at least once.

Power warranty – A power warranty or performance guarantee ensures that your solar panels output a specific amount of energy over their lifetime. It’s normal for panels to degrade over time, failing up to 1% per year. Companies offer linear power warranties to ensure a consistent level of degradation per year. These types of guarantees ensure a consistent level of degradation per year. Some solar companies will feature a stepped warranty, which includes coverage for a flat rate and decreases at different stages of the solar system.

Depending On The Type Of Roof You Have And Aesthetic Considerations There Are Different Ways To Mount Solar Panels On Your Roof Here’s An Overview Of The Choices

The most visible part of a home solar system is the panels. Around 95% of homeowners choose a roof-mounted system, so how the panels are attached to the roof is a key detail of the installation.

Solar panels are attached to a roof using a mounting system. The most common type is a rail-based system, which uses aluminum rails as the structure onto which the panels and other components, such as wiring and inverter components, are attached. These rails in turn are attached to mounting points called footings that are bolted into the structural beams of the roof.

Another type that is becoming more popular is a railless mounting system. As the name suggests, railless systems dont have rails onto which the equipment is mounted. Instead, the solar panels are attached directly to footings that are fixed to your roof.

There are pros and cons to both types of mounting systems. While there are aesthetic considerations that might cause a homeowner to ask their installer to choose one type over another, technical demands will usually be the deciding factor. In addition, whether you have shingles, tiles, or metal on a flat or pitched roof will often dictate how your solar panels are mounted to your roof.

This is a pretty complicated topic, so Ill link to other articles Ive written that are specific to particular roof types. But first, lets start with the basics of how solar mounting systems work.

If you have enough to make a cash purchase, youll save more than with any other option but even with a zero-down solar loan, your savings could still be in the tens of thousands.

South Is Best Direction To Maximize Solar Panel Output

How to install solar panels yourself on your roof. (It’s easier than you think)

In the Northern Hemisphere, where the United States is located, solar panels will achieve maximum possible electricity production when they are facing south.

Thats because, on average, the sun shines directly over the Equator over the year. If youre north of the Equator, facing south towards it will maximize exposure to sunlight. In fact, in all regions north of the Tropic of Cancer – which includes the entire mainland U.S. – the Sun moves across the southern half of the sky all year round.

In other words, solar panels oriented south in the United States will face the sun all year long.

Pictured: The furthest north the suns path travels is directly over the Tropic of Cancer, roughly 23.5° north of the Equator, during the summer solstice . As all of the mainland U.S. is located north of the Tropic of Cancer, the sun shines to the south for us all year-round.

What To Do If Your Roof Has Between 5 And 15 Years Of Life

If your roofer estimates that your roof is in the middle range of its remaining lifespan – around 5 to 15 years of life left – then your decision is a little tricker. You donât want to replace your roof too early, otherwise youâll be throwing away useful life of your roof.

But if you delay going solar, you can also be giving up the energy savings that come with generating your own electricity. So how do you decide?

The best thing you can do is to understand exactly how much money you can save with solar by finding out your payback period. The payback period is simply how many years a solar panel system will take to pay back your initial investment in the system through annual energy savings. Depending on where you live, high electricity prices and local rebates can push your payback period to as little as 5 years.

On the other hand, there are some places in the US where a lack of rebates and low electricity prices can make your solar payback relatively long – 15 years or even longer.

You can estimate your payback period quickly by using The Solar Nerd calculator. Just plug in your zip code and details about your roof, and itâll show you a graph of how many years it will approximately take for you to break even on your solar investment.

The calculator is a tool for doing a quick estimate on your own. For a more accurate assessment, contact multiple solar installers, who will each give you a system proposal and power generation estimate.

Which Angle Is Best For The Solar Panels

The best angle on your solar panels depends on where in Sweden you live. If you want to install solar panels on a roof in northern Sweden, we would recommend an angle of 35 degrees. However, if you live in southern Sweden, we recommend an angle of about 45 degrees to get the maximum effect from your solar panels. As a reference, an “average villa roof” usually has an angle of 40-45 degrees, which is excellent for solar panels.

In the table below you can see how the combination of direction and angle of the roof affect the effect of your solar panels.

However, we want to emphasize that the angle of the roof does not affect the production of solar energy to the extent that one can imagine. If your solar panels have an angle that differs up to 10 degrees from an optimal angle, it will only produce about 2 percent lower output than the maximum. Given that you do not have dirt or snow on the solar panels..
