Grid-tied vs Off Grid
Why Do You Want Solar?
Everyone has different reasons for installing solar. How you answer this helps us recommend the right system for you. Previously, 95% of our customers wanted to reduce their electric bills with a straight grid-tied system, but we are finding more and more people who want the security and reliability of creating and storing their own energy. We can help you do this.
Battery-based systems are a great choice in Texas
Battery systems are now financially viable and easier than ever to operate. No longer the system exclusively for those who wanted to disconnect from society, these systems are now mainstream options for many who contact us.
Others talk about backup: we understand it and know how to install the most robust, reliable systems in Texas.
We have the ability and knowledge to install everything from simple single inverter systems to “multi-stacked” inverter setups like you see to the left, able to back up an entire ranch.
The two Essential Questions to Ask Yourself:
1. Do I have essential systems that MUST keep operating during electric disruptions?
2. Do I recognize that when I select batteries, there is an unquantifiable benefit that will cost more than a straight grid-tied system?
The most important question is, "Do I want power when others might not have it?"
If the answer is yes, please let us show you options to meet your reliability and security requirements.
The choices for "grid-tied" PV systems
Solar CenTex installs “grid-tied” solar PV systems which means you are still receiving a portion of your electricity from your current Retail Electric Provider (the “REP”). The amount you get from your REP is entirely dependent on the size of the PV system that is installed: typically expect that 30% to 99% of your electricity needs can be met by solar.
Batteries are so much more than backup. Batteries and modern inverters provide advanced home energy management and this picture illustrates this on so many levels.
1. “Peak Shaving” at the 8PM peak is this system providing stored solar to offset an evening demand for power. He has one LG battery so he can get 6,000-watts of offset. (Two batteries would have provided additional peak power.)
2. He does not have this at 8AM because we programmed his battery to retain 30% capacity for actual grid outages (we can select any reserve level) so while his battery had the potential to provide the power, the system took power from the grid instead.
3. His 17KW system produced 108kwh and his home used 70kwh this day. Of that 70kwh, nearly one third was provided by stored solar energy.
This is just one day but shows a home that is using the energy storage as so much more than backup.
This will “future-proof” him from whatever time-of-use rates that Texas throws at him in the years ahead. All while having peace of mind no matter what Mother Nature serves up to the grid reliability.
Great warranties (25 years for the DC Optimizer, 12-20 years for the inverter)
- Ability to monitor the power output of individual modules
- Much better shade tolerance
