Frequently Asked Questions About A Solar Installation


How does solar work?

Solar electricity works exactly the same as the electricity you buy from the utility company. In fact, if you didn’t see solar modules on the roof, you’d never notice any difference, except a lower electric bill. Solar electricity is generated by a group of solar panels called an array, or solar installation, that when is exposed to light, instantly generates a Direct Current (DC) electrical current, which is then fed into an inverter that converts it to the Alternating Current (AC) electricity that the utility supplies to your home.

The home uses the power generated by your solar array first, supplementing any additional power required from the grid - and sending excess power generated back to the grid, resulting in a credit on your bill.

For instance, if your electricity provider is TVEC (Eastex Solar's provider), expect to receive about a $0.065 per kWh credit on your bill for excess generation. If you're in the DFW or Houston Metro area, TXU, Reliant and Green Mountain Energy have plans that result in a one-for-one credit for excess power! 

What does it cost to install?

As you'd expect, the cost of a solar installation depends on a number of factors including whether it's ground-mounted, or roof type (metal or shingle), steep pitch or flat, along with system size and what percentage of your power you want solar to provide.

However, I know you want a $$ figure, so here goes:

1.) Our average system size consists of 30 solar panels, or 9,000 watts, or 9kW.

2.) This system will generate an average of 1200 kWh in central and east Texas.

3.) Total installed cost will average $18,000, or $12,600 after the 30% Federal Tax Credit.

4.) Annual savings TODAY amount to $1,400 - $2,100, depending on electricity provider.

5.) System pays for itself in 6 - 9 years, depending  on orientation and  other factors.

Solar modules are warranted to produce energy for 20-25 years. Over that time period, the cost of electricity from the utility will increase, while the solar system produces power from fuel that is free. Additionally, a solar electric system increases the home’s value due to the reduced operating costs - and that increase in value is exempt from taxes in Texas.

Frequently Asked Questions About Solar Installations

Most of our installs are completed in 1-2 days, larger systems and ground-mounted projects will take longer of course. From contract date to install, expect your solar installation to be energized within 30 days. HOA approvals, and/  or permitting issues may extend the period necessary to receive Permission to Operate.

What about maintenance?

Occasionally, a solar array should be cleaned to clear the dust, pollen or debris that blocks sunlight and reduces efficiency. That is about all that’s required. There are no moving parts to wear out and solar modules are covered under limited warranty for power output for 20-25 years. In fact, there are solar modules that have been installed 50 years ago that are still producing energy today.
