How much do solar panels cost in Pittsburgh in 2017?

installing solar panels in pittsburgh pennsylvania

The past decade has seen astounding growth in the U.S. solar industry across the board, but a few key states have led the way. Though many stakeholders are aware of the popularity of solar in sunny states like California, Florida and Arizona, very few are aware that Pennsylvania is one of the top states for solar in the country with some of the industry’s best prices. Over 34,000 PA homes are currently powered by solar and the state has witnessed a 64% decline in prices over the past 5 years. In this article we’ll explain what to expect a solar installation to cost in Pittsburgh and offer some advice for solar shoppers in the greater Pittsburgh area.

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.

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.

Does my solar roof have to face south?

You don’t need optimal conditions for your solar power system to be a great investment. One of the biggest myths about the financial viability of solar is that it requires a really sunny location and a south facing roof. While these may be ideal conditions, folks outside of Southern California with roofs that face other points on the compass, such as east to west-facing roofs, can still satisfy most of their electricity needs and reap significant financial returns when they adopt solar power systems.

What is the power output of a solar panel?

power output of a solar panel

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 a 300 wattage.” 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?

This piece will explain how solar panel ratings work so you can better compare your solar options. 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 solar panels on the market today have power output ratings ranging from 200 to 350 watts, with higher power ratings generally viewed as being more favorable than lower power ratings. Pricing in solar is typically measured in dollars per watt ($/w), and the wattage of your solar panels plays a significant part in the overall cost of your solar system.

How do SRECs work? Solar Renewable Energy Credits primer

Of all the incentives for installing solar panel systems, solar renewable energy certificates (SRECs) are some of the most potent, yet least-understood. You may have heard enigmatic terms like “SREC markets,” “solar renewable portfolio standards,” and “minimum compliance payments” thrown around in discussions about SRECS, but sifting through of all this jargon can be downright mind-numbing. However, SRECs can provide sizable streams of money to owners of solar power systems, so learning about what SRECs are, where they are available, and how they can make solar more financially-rewarding can, quite literally, pay off in a big way. In this article we aim to answer the simple questions: “how do SRECs work?”

Solar Panels For Apartment Renters: Can You Get In On Clean Energy’s Financial Benefits?

solar panels for rental properties

The simple answer for renters who want solar panels for their apartment or home is that it is possible. Through a number of methods, a renter can still cash in on the financial benefits of solar even if they don’t own their property.

If you’re renting and paying your own utility bills, you may think that there’s no incentive for your landlord to switch to a system powered by clean energy. But, switching to solar photovoltaics, solar thermal, wind power, geothermal, biomass or combined heat and power could be a win-win situation for you and your landlord. You already know you, as the tenant, would benefit by limiting future increases in your utility bills. But can you really convince your landlord that it’s in his or her best interest, too? The answer is a resounding “Yes!” All you need to do is present a compelling case. So, here’s how:

How Roof Angle Can Affect Solar Panel Performance

There are a lot of factors that can affect the performance of your solar panels and the economic benefits they can generate—things such as where you live and how sunny it is, how much you pay for electricity, which way your house faces—even the pitch of your roof. Variety is the spice of life, but the diversity of our architecture can affect the performance of solar panels. It’s important to understand how those differences in production performance related to the angle of your roof will affect the overall financial performance of your solar power system.
