The process of of how solar installers design a solar energy system is often a mystery for most consumers. Because of this, we would like to give you some insight into how solar installers design a solar power system for your home or business. A solar power system is designed considering two important factors – the amount of space that you have available for installing solar panels and the amount of electricity you consume annually. Other factors, like shading analysis and the efficiency of solar panels and inverters also come into play. Continue reading
Until just recently, Texas was not even among the top 10 states for solar energy, thus many were surprised when the Lone Star State was ranked #3 in the U.S. for solar jobs in 2016. Texas is adopting solar at one of the fastest rates in the country, and for good reason. Prices dropped 20 percent last year, and a number of utilities across the state launched or extended major incentive programs for solar PV systems. In this article we’ll break down Texas solar prices and use a case study to explain how comparison shopping can help homeowners get a better deal.
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.
Power output or wattage is an important factor to consider when comparing solar panel options. You may hear your solar installer say, “it’s a 255 Watt panel” or “the panel I am recommending is has a wattage of 300.” Or, when you are reading a quote from a solar installer, you might see numbers like 245W, 300W, or 345W next to the name of the panel. They are all referring to a solar panel’s wattage, capacity and power output. So, what is the typical output of solar panels?
All solar panels are rated by the amount of DC (direct current) power they produce under standard test conditions. Solar panel power output is expressed in units of watts (W), and represents the panel’s theoretical power production under ideal sunlight and temperature conditions. Most home solar panels on the market today have power output ratings ranging from 250 to 400 watts, with higher power ratings generally considered preferable to lower power ratings. Pricing in solar is typically measured in dollars per watt ($/W), and the total wattage of your solar panels plays a significant part in the overall cost of your solar system.
Solar adoption is skyrocketing in the United States. Partly responsible for this surging uptake is one of the oldest industry drivers: word of mouth marketing. The SolarCity Ambassador Program, EnergySage Rewards Program, and others are a big part of this growth. Continue reading
People say all the time that they want to get off the grid. Beyond just meaning getting away from it all for a while, getting of the grid has a specific technical meaning with regards to your relationship to your utility and how you get your power. So, what exactly does it mean to go off the grid? Continue reading

When you’re installing a solar energy system, a lot of variables impact the price. Even if you and your next-door neighbor have solar systems that are the same size, you may end up paying very different prices. We’ll walk you through what variables change the price of your system so you can understand what will be the best system for you. Continue reading
