Why are solar panels so expensive? Understanding the cost of a solar panel system

The Cost of a Solar Panel System

While the most expensive part of going solar is paying for the equipment, it still only represents 25 percent of the overall expense. Soft costs, or the outlays that installers spend just trying to find you and appeal to you, also contribute a significant percentage. Here’s a breakdown so that you can understand the cost of a solar panel system, plus tips on how you can save money!

What to Know About a Solar Panel Warranty

What is a solar panel warranty?

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. SunPower offers the best warranties.

A solar panel’s product warranty insurance covers the integrity of the panel itself, and protects you against problems such as manufacturing defects, environmental issues, premature wear and tear etc. As with most warranties, a longer period is generally more advantageous to you, if you own your solar panel system. When evaluating a solar panel warranty and its manufacturer, the two most important factors on which you should focus are:

1. Product (or materials) warranty, and
2. The performance warranty
We’ll address both of these in this article as we break down our process for finding the best solar warranties offered by manufacturers.

Comparing Solar Panel Racks: Unirac, IronRidge, Quick Mount PV & Ecofasten Mounting

types of solar panel mounting

Solar panel racks like IronRidge and Unirac PV mounting apparatus are critically important but lesser known components of a solar panel system. When it comes to installing solar on your roof, there’s plenty of information available to help you compare solar panel options and inverter technologies. Some solar installers are even starting to offer different options for solar-plus-storage products that include a home battery. However, not much has been written about the various solar panel rack options available to mount the system on your roof. While these items don’t typically have a significant impact on your solar system’s performance, solar panel mounts are still an important part of the installation process. Read on to learn more about the top solar panel mounts from Unirac, IronRidge, and SnapNrack, as well as specialized products from Quick Mount PV, Ecofasten, and AllEarth Renewables.

Best solar battery chargers: marine, RV and car battery chargers

solar battery chargers for phones cars and boats

Among today’s many uses for solar energy, one increasingly popular way to harness sunlight is with battery chargers that can power common home products. Outside of rooftop and utility-scale photovoltaics (PV), battery chargers might be the next best use for solar energy in terms of efficiency and practicality. A small panel can easily be placed next to a window to charge a phone, and a portable charger can be an easy way to power your car’s battery through the sunroof. In this article we’ll discuss the many ways a solar battery charger can be useful, including how solar works with cars, boats, RVs and small devices.

Key metrics for comparing solar panels: PTC solar, STC rating and temperature coefficient

So you’ve made the decision to go solar. Well done! If designed right, a solar power system is a great, long-term investment with both financial and environmental benefits.

Choosing the right solar panels is one of the most important steps in designing your solar power system. There are hundreds of options, and while all panels are designed for one purpose – to convert sunlight directly into electricity, not all panels are created equal. Different solar cell technologies and the quality of manufacturing can impact the performance of ysolar panel quality and performance energysageour panels. For these reasons, comparing solar panels and finding the right one to meet your specific system needs can sometimes be a complicated task; but, it doesn’t need to be.

In this article we’ll explain important metrics like PTC power rating, STC, degradation rate, efficiency and temperature coefficient.

Best solar inverters review: SolarEdge vs. Enphase vs. SMA vs. Tigo

best solar inverters enphase vs solaredge vs sma

If you want to maximize your solar energy system’s production, finding the best solar inverter is as important as the solar panels you choose. For an “uncomplicated” roof – one that faces south and has no gables, chimneys, or other obstructions that can cast a shadow – the best solar inverter for you may be a standard string inverter. However, more than half of new residential solar installations are using module-level power electronics (MLPEs) like power optimizers and microinverters to maximize electricity production.

How do inverters work? Comparing solar inverter technologies

how inverters work

Solar panels aren’t the only component that you should be thinking about when you evaluate your solar system equipment. Inverters play an equally important role in a solar energy system: they convert the electricity your solar panels create into a form that can be used by the appliances, lighting, and other electronics that are in your home. Once you understand how inverters work, and the different types of inverters available for solar, the EnergySage Solar Marketplace can help you compare solar quotes with different inverter types.
