Bluebonnet Electric Solar Information

Providing Solar To Bastrop, Elgin, & Smithville Texas

Providing Solar To Bastrop, Elgin, & Smithville Texas

Bluebonnet Electric Cooperative (BBEC) provides electricity to areas east of Austin, including Bastrop and East San Marcos TX.  HESOLAR Owners, Derrick and Eric Hoffman, are from Bastrop and have provided electrical service in the Bluebonnet area for over 15 years. The easy application process and close proximity of Bluebonnet allows HESOLAR to offer low, competitive prices that are comparable to utilities with a solar rebate.

Bluebonnet Solar Information

Returned Solar Tariff:  Bluebonnet has two rate on their meters:

• Delivered Energy: $0.087 /kWh. This is the cost for consumed electricity.
• Returned Energy: $0.063 /kWh. This is the credit you receive for solar energy fed in to the grid.

Solar Tariff vs Net Metering: A Solar Tariff’s benefit will depend on whether it is more or less than the Delivered Rate. Right now the Tariff is lower meaning that excess solar energy not consumed by loads will be credited less than you could buy the energy for. Below are key-points for understanding Bluebonnet’s Solar Tariff:

• Bluebonnet allows previous solar owners to use net-metered billing. All consumers moving forward (September 2017) Will be limited to the Solar Tariff Option.

• The Solar Tariff Rate will be recalculated every August.

• HESOLAR typically saw a 10 to 12 year Return on Investment for solar power systems in the Bluebonnet territory with Net-Metering. We will no longer be able to estimate Solar Returns because we will not know how much solar energy your home or business will consume… unless you have energy storage (more on that below).

• Return on Investment is the amount of time it takes for solar energy savings from electricity bills to pay off the system (i.e. $126/month savings for 120 months). Our Solar Panels carry a 25 year warranty meaning consumers save money every month after hitting their break even point.

• Hypothetically consumers could still have a 10 to 12 year Return on Investment with Solar Tariff if they knew they were consuming or storing all excess solar energy that their home didn’t consume.

• Energy Storage adds cost but can allow consumers to capture excess electricity and use it in the evening when their solar panels are no longer producing. These systems are gaining popularity because the offer backup power during power outages. HESOLAR Battery Systems allow consumers to recharge their batteries with solar panels… if the system is large enough you will essentially be off grid!


Federal Tax Credit: The federal tax credit provides a 30% tax credit for people and businesses that have tax liability (you pay taxes). The Federal Tax Credit is 30% of the total system cost for solar installation. More information on the Solar Tax Credit on the

Tax Credit Example: If a Customer purchased a 6KW Solar PV System for $18,000. The Federal Tax Credit would be $5,400. Note: Pricing Varies
