Incentives

Federal Incentives

The inflation reduction act has made the federal tax credit available to institutions that do not carry a tax burden. This is done through either Direct Pay, or though a Transfer of Credit.

Direct pay is available to most tax exempt organizations, such as local governments, school districts, tribal governments, 501(c)(3) organizations, 501 (d) organizations, and other organizations under 501(a).

Direct pay allows for tax exempt organizations to get a payment equal to the full value of the tax credit they would have otherwise received for installing solar, which is 30% of the full installation and purchase cost.

Transfer of Credit allows for credits to be sold to other entities. However, this method is much more complicated than the direct pay option. If you are interested in transfer of credit, talk to your tax professional.

Net Metering

What is Net Metering?

People often connect the concept of solar to the concept of going off-grid and using battery backups. However, the most common residential solar systems are grid-tied. 

In the grid-tied design, your solar system provides power to your home and any excess electricity generated beyond your energy use is delivered back to the utility grid. If your solar PV system is not producing enough energy to meet your needs, (e.g, at night when there is no sun), then you use electricity from you utility.

Grid-tied is the least expensive type of system design. It also allows for net metering – which is how you make money from your utility when they buy back your extra energy from your solar array, which appears as a credit on your electric bill. 

In essence, net metering is your electric meter spinning in reverse.

Some months, your solar array will generate more energy than you use and other months you will be using the grid plus your solar array for energy consumption. 

Net metering still works to save you money over the course of the year as your credit for excess production rolls over to future months.

Net metering policy can vary by region.

Owning Solar: FAQs

Storage

Can I use a solar battery with my existing solar panel system?

In most cases, solar batteries can be integrated with existing solar panel systems. However, it is recommended to consult with a solar installer to ensure compatibility and proper installation.

How long do solar batteries last?

The lifespan of a solar battery depends on several factors, including the type of battery, usage patterns, and maintenance. On average, solar batteries can last anywhere from 5 to 15 years. It’s essential to consider the warranty and performance guarantees provided by the manufacturer before making a purchase.

Can I get financial assistance for purchasing a solar battery?

There are various financial incentives available to help offset the cost of solar batteries. These include federal tax credits, state rebates, and utility-specific programs. It’s recommended to research and explore available incentives in your local area or consult with a solar professional who can guide you through the process.

Solar Panel Maintenance

What kind of maintenance does a solar system require?

Solar systems require little maintenance due primarily to having no moving parts. A tracking system of a pole mount array does contain moving parts and has the potential to require maintenance. Many battery backup systems also require maintenance to ensure battery longevity. Work with your installer to set up an operation and maintenance plan to ensure that the system is operating at optimal capacity.

 

Do I need to clean snow off of my solar panels?

Any shading to a solar panel will reduce electrical output. Solar panels can still produce while covered by a very light snowfall, but any more than that and the panel will not generate electricity. Solar panels have a slippery surface and are positioned on an angle. This can help snow slide off as the sun melts it. Ground mounted solar arrays can easily be brushed clean after a snowfall. If you have an off-grid system and depend on every photon, getting on the roof and dusting off your panels with a broom may be necessary (with proper safety restraints of course).

 

How long do solar panels last?

Most solar modules are guaranteed to last 25-30 years, and even after that, we are seeing efficiency output of 80+%. The kilowatt output degrades slightly each year yet can continue to provide consistent output. Most solar manufacturers provide a performance warranty of 25-30 years. Other PV system components, such as an inverter, could possibly need replacing during the lifetime of your array. Inverters often carry a warranty of around 10-12 years.

 

Sizing

How do I determine the right size for my solar system?

Determining the size of your solar system involves assessing factors such as your energy consumption, available roof space, and local climate conditions. It is recommended to consult with a solar installer who can conduct a thorough assessment and provide accurate sizing recommendations tailored to your needs.

What factors should I consider when sizing a solar system?

When sizing a solar system, you should consider your average energy consumption, peak energy usage, available roof space, shading, and the orientation and tilt of your roof. These factors will help determine the number of solar panels.

How can I estimate my energy consumption?

To estimate your energy consumption, review your utility bills to determine your average monthly kilowatt-hour (kWh) usage. You can also use online calculators that consider factors like your location, household size, and energy usage patterns to provide a rough estimate.

What if my energy needs change in the future?

It’s important to consider future energy needs when sizing a solar system. If you anticipate changes such as an increase in energy consumption or the addition of electric vehicles, inform your solar installer. They can design a system that accommodates future changes, ensuring your solar investment remains viable in the long run.

Schools

How can I add solar into curriculum?

  • The Wisconsin K-12 Energy Education Program (KEEP) was created to promote energy education in Wisconsin
    schools. They have a host of free, downloadable solar curriculum and activities organized by grade level as well as
    classroom visits, hand-on lending, and partner programs. Activities are categorized by age group and offered to
    students in elementary through high school.
  • Center for Renewable Energy Advanced Technological Education (CREATE) has a host of downloadable curriculum
    and in-person teacher training. Each of their teaching materials include teacher lesson plans, student handouts,
    answer keys, and resources for each of the lessons explored. Documentation is also provided for each lesson
    referencing the U.S. DOE Energy Literacy Standards (ELS) and the Next Generation Science Standards (NGSS).
    Curriculum is intended for an 8th-12th grade audience.
  • The MREA’s Solar Corps initiative has partnered with Technical Schools to help colleges across the Midwest establish
    solar career pathways for students. The Solar Corps is a regional workforce partnership designed to assist colleges
    with two common needs: providing hands-on and work-site experience for students and supporting student job
    placement and professional certification to advance in the solar industry.

 

How much will solar on my school cost? 

A typical school-sized PV system (100 kW – 300 kW DC) will cost less than $2 per watt (as of 2021), often at $1.50-1.60
per watt. For example, a 100 kW DC sized system would likely cost less than $200,000. You can use these estimates when
estimating how much various system sizes will cost.

Solar on Schools

Solar on Schools

The Midwest Renewable Energy Association, in partnership with the Couillard Solar Foundation, offers Solar On Schools to Wisconsin schools. Solar on Schools was developed to provide a range of resources to Wisconsin schools, assisting with and simplifying the solar project development process. The program aims to help Wisconsin schools realize the financial, educational, and community benefits of going solar.

Solar Storage

Solar Storage

Solar storage, offers an alternative to net metering. While net metering allows you to sell excess solar energy back to the grid, solar storage allows you to store that excess energy for later use. This means you can harness the power of the sun even when it’s not shining, giving you greater control and independence over your energy consumption.

Solar storage can come with a larger price tag compared to net metering. With solar storage, you can maximize your energy savings by avoiding peak electricity rates and reducing your reliance on the grid. Plus, you’ll have peace of mind knowing that you have a reliable and sustainable source of energy, even during power outages.
