Solar Program in General

How can I calculate my savings?
Rule of thumb: 1 kW system in Orlando is expected to produce an average of 1350 kWh a year. (Source: National Renewable Energy Laboratory – PVWatts)

Calculating savings for solar thermal:

A 40 SQFT solar thermal collector equivalents to roughly 2 kW.

I want to install a 40 SQFT solar thermal collector, how much will I save?

40 SQFT collector equivalents kW: 2
1 kW System Production kWh/yr: 1,350
1,350 kWh x 2 = 2,700
2,700 / 12 (no. of months in a yr) = 225
225 * $0.11 (OUC rate) = $ 24.75
Total monthly savings $ 24.75
Total yearly savings $ 297.00

Calculating savings for solar photovoltaic: An average residential solar system is about 4-5 kW.

I want to install a 4 kW photovoltaic solar system, how much will I save?
Solar system size kW: 4

1 kW System Production kWh/yr: 1,350

1350 kWh x 4kW = 5,400
5,400 / 12 (no. of months in a yr) = 450
450 * $0.11 (OUC rate) = $ 49.50
Total yearly savings $ 594.00

If I use about a 1,500 kWh a month, what size solar system should I get to offset my usage?
1 kW System Production kWh/yr: 1350

kWh Monthly Electric Consumption: 1500

1,500 * 12 (no. of months in a yr) = 18,000
18,000/1,350 13.33
Total kW needed 13.33

Where can I go to find out more information about solar?

If I already installed a solar system on my home/business, can I still participate in OUC's Solar Programs?
Yes, for the PV program. Depending on how old the system is, a solar contractor would need to bring the system up to code so that it can pass OUC's inspection. For solar thermal systems, applications must be submitted within 6 months of system installation. Visit the Residential How to Apply or Commercial How to Apply section to learn more about the requirements.

How much do solar systems cost?
Solar Thermal – an average 40 SQFT open loop collector with an 80 gallon tank can cost $4,000 - $5,000.

Solar photovoltaic – around $4 - $6 / watt. For example, a 4 kW system can cost $16,000 - $24,000.

Cost can vary on market prices. Please contact a certified solar contractor to get specific pricing costs.

Why does OUC  verify/inspect the solar system?
OUC needs to verify that all solar photovoltaic systems interconnected to our grid are installed safely and will not jeopardize the safety of our crew working in the area.

In addition to OUC's solar incentives, what other rebates are available for solar systems?
Rebates and incentives vary by where you live. Please visit the DSIRE website to see what incentives are available in your area: http://www.dsireusa.org

What paperwork does OUC need in order for me participate in the solar program?
Please visit the Residential How to Apply or Commercial How to Apply sections of our website to see the list of requirements.

If I am an OUC water only customer, can I still participate in OUC's Solar Programs?
No, participation in OUC’s solar programs requires customer’s electric service be provided by OUC.

Does OUC install the solar system?
No, OUC does not offer a program where we install solar systems for the customer. We do, however, have a list of solar contractors through our Preferred Contractor Network.

What kind of permits are required?

  • City of Orlando requires a building and electrical permit for PV and a building and plumbing permit for Thermal.

  • For more information, visit the City of Orlando permitting website.

  • Orange County requires an electrical permit for PV and a plumbing permit for Thermal.

  • For more information, visit the Orange County permitting website.

  • St. Cloud requires an electrical permit for PV and a plumbing permit for Thermal.

  • For more information, visit the St. Cloud permitting website.

  • Osceola County requires a building and electrical permit for PV and a building and plumbing permit for Thermal.

  • For more information, visit the Osceola County permitting website.

Solar Thermal FAQs

Is OUC's Residential Solar Thermal Program an incentive or a rebate?
OUC's Residential Solar Thermal Program offers a $900 rebate.

What is a point-of-sale rebate?
The OUC Solar Thermal point-of-sale rebate is a rebate only an OUC Preferred Solar Contractor can provide to you at the time of purchase. The OUC point-of-sale thermal rebate is $900.

Can I use any solar thermal contractor I choose and still participate in OUC’s Residential Solar Thermal Rebate Program?
Yes. OUC’s Residential Solar Thermal Program was created to encourage residential solar thermal system installations. To select an OUC Preferred Solar Contractor to install your system, click here. However, customers who use contractors not participating in the OUC Preferred Contractor Network are eligible to participate as well.

Why is it required to have OUC verify a residential solar thermal system?
OUC needs to inspect the solar thermal system to verify the solar system installed matches the equipment listed on the application.

Solar Photovoltaic FAQs

Why is it required to involve OUC when installing a photovoltaic system?
OUC needs to be aware a solar photovoltaic system will be interconnected for the safety of our crew working in the area and manage the impact of solar projects on our grid. Additionally, OUC will verify that the metering equipment is capable of supporting a photovoltaic system.

What type of meter does a photovoltaic solar system need?
The existing electric meter will be replaced with a bi-directional meter for net metering.  To learn more, visit the How to Apply section and the Solar Installer Information section.
