Texas’ electricity infrastructure is quite an anomaly when compared to most states. Instead of one electricity company both generating the electricity and maintaining the equipment to get it to you (poles, wires, transformers, etc), Texas is a deregulated market.
As such, Texas residents can purchase electricity from any electricity generation company they choose, though one company (Oncor in Dallas) is responsible for maintaining the local electricity grid.
Deregulation was meant to lower electricity prices for customers by introducing competition into an industry that has historically been dominated by quasi-monopolies regulated by the state.
In Dallas, you can choose from dozens of electricity providers. Some provide the cheapest electricity possible, while others are more expensive but offer incentives or bonus programs. Some even sell 100% clean energy (Green Mountain Energy, for example).
All this is great, but what if you want to produce your own electricity by installing solar? In this unique market, what kind of return could you see and how much would it cost? Does Dallas or its utilities offer any special incentives for going solar?
Do you live in a sunny state and think that solar panels may be a good investment to cut down on your energy bills and improve the value of your home? Or maybe you live in a less sunny state and believe solar panels would be suicide from an investment perspective. In reality, the decision to go solar is more complicated than just calculating sun hours per day by zip code.
Let’s figure out what is important to know about sunlight before you decide to go solar. Continue reading
Can you use solar panels to run air conditioner units? In a word, yes. If your home is connected to the grid and your solar installation is net metered, it is possible to use solar energy to cool your house. Many homes already do this!
Let’s take a look at AC energy requirements and typical solar production to see if solar panels can really run air conditioners in each setup.Continue reading
Solar inverter efficiency determines how well an inverter converts the DC electricity created by solar panels to AC electricity that can be used in our homes and by the grid. Inverters are an integral part of any solar installation. Without them, our installations would actually be useless, since we couldn’t use the electricity they produced.
No inverter is 100% efficient, as there will always be at least some loss of energy during the conversion process. However, inverters today enjoy very high efficiency, converting between 95% to 98% of all the DC electricity generated into AC, with manufacturers always reaching for that next step in performance.
Is solar inverter efficiency really that important? Is it worth spending a couple extra bucks for the most efficient solar inverter you can find? Let’s take a look at inverter efficiency to answer these questions and more!Continue reading
Residential solar installations run from a measly 2kW to a monstrous 25kW (or even bigger). Twenty-five kilowatts (kW) is a huge solar installation (at least for residential projects), equal to about 100 solar panels.
Don’t have that much space on your roof? Don’t worry! Most installations, such as the 5kW solar system, are well below that size. Most of us don’t even use enough electricity to warrant an installation that big! In fact, according to the National Renewable Energy Lab (p.5), the average installation is about 5.6kW.
Today, let’s take a peek at a 5kW installation to understand exactly how big that is, how much you can expect to pay for one, and how much you can save by installing a system of this size.Continue reading
There’s actually a few different options for purchasing solar panels, from simply paying cash to taking out a loan or lease.
Which one’s best? Let’s run through each and discuss their pros and cons, as well as which one you should choose and why.Continue reading

If you’ve received quotes or savings estimates from solar installers, you’ve probably noticed that your current electricity price is listed somewhere on the page. Next to or below that price, you’ll probably also see the phrase estimated utility rate increase, expressed as a percentage.
Typically, it’s something like “Current electricity price: $0.13 per kWh. Estimated utility rate increase: 2.5%”. If you’re like me, you’re probably wondering what this rate increase is, and if it’s really that important.
To keep it simple: Yes, it is!
Today, you’re getting a crash course in energy price increases. I know, I know. It sounds boring. But, by the end of this article, you’ll be able to rest assured knowing that your savings estimate is – or is not – an accurate look at your future savings. It’s that important!Continue reading
