How much do solar panels cost in Texas in 2017? Case study, incentives and pricing

solar prices and solar panel installation in texas

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 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.

What is an SREC? Net metering credits explained

what is an srec graphic People often think SRECs and net-metering are the same thing, but really, the comparison is like apples to oranges. It’s true that they are both important to getting the best financial results from your solar PV system, but SRECs and solar net-metering actually have very different, distinct functions.

SRECs are a way to put cash in your pockets while net-metering is an efficient way to manage the finances related to your utility bill. Both can have positive financial effects and understanding the difference between the two can help you, as the owner of a solar PV system, to maximize the benefits of both. Here’s how it all works: Continue reading

Mitsubishi solar panels: the complete review

Mitsubishi solar panel review

Mitsubishi Electric is one of the world’s largest manufacturers of electronics and electrical equipment, including televisions, air conditioners, and solar panels. The company was founded in 1921, and it manufactured the first solar panels to provide power to satellites in the 1970s. All of Mitsubishi’s solar panels are manufactured in Japan. Although they are relatively new to the U.S. market, Mitsubishi solar panels are increasingly popular in quotes to solar shoppers comparing their options on the EnergySage Solar Marketplace.

Top Community Solar States: Minnesota vs California vs Colorado Community Solar

comparing the top states for community solar graphic

Community solar – the concept of leasing or owning a share of a large solar array rather than having a personal solar installation on your rooftop – continues to gain popularity across the continental United States. According to the Solar Energy Industry Association (SEIA), there will be a 1.8 gigawatt (GW) increase in installed photovoltaics from community solar arrays over the next five years.  Minnesota, Colorado and California – the undisputed best states for community solar – will drive the majority of that growth. You might wonder, why are these states so ideal for roofless solar compared to the 47 others in the U.S.? Here’s how these community solar leaders rose to the top.

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.
