Nevada is an excellent state for solar energy generation, enjoying over 250 days of sunshine a year with very few clouds in the sky. Homes in nearly every neighborhood now shine with solar panels. Older homes, however, may face a few extra challenges.
The oldest homes in Nevada were built in the 1850s, with homes from every era since then. While older homes have a lot to gain from supplementing their power use with solar, old roofs and electrical systems should be carefully considered.
Roof Structural Challenges
Older roofs are less likely to be solar-ready. Consider your roof’s current age and integrity in terms of weight-bearing capacity and how long before you’ll need a new roof. You may need roof repairs first, and the best time for solar panel installation is right after you install a new roof.
You may also need to consider roof orientation and shading issues. Older homes are often shadowed by tall older trees or more recently built taller buildings. Lastly, older roofs may have limited space or smaller surface areas for solar panels.
Electrical System Integration
Be very careful adding solar to outdated electrical panels and old wiring. Old circuits may have capacity issues and it may be necessary for a complete electrical upgrade before you add solar power generation.
Consider grounding and bonding requirements for electrical safety – which may not have been required when the home was built. You will also need to consider how to integrate solar power with older electricity meter systems.
Aesthetic Considerations
Historical neighborhoods may not encourage solar on the roof. Historical preservation regulations and restrictions may limit your options. Consider the visual impact of solar on older architectural styles. Explore creative solutions for maintaining the character of your home while still enjoying solar – like solar panels in the yard or mounted on a newer garage roof instead.
Energy Efficiency Gaps
The oldest Nevada homes tend to be “breezy” to say the least. They often have much lower energy efficiency ratings with less insulation and hidden cracks that reduce the effectiveness of HVAC. Outdated HVAC systems also drain electricity with much less efficient or badly aged processes.
Consider the impact of solar panel efficiency and sizing on your energy profile. Improving the home’s overall energy performance with insulation, sealing, repairs, and HVAC upgrades can improve the beneficial impact (and reduce the necessary size) of your solar installation.
Financial Considerations
Solar installations on older homes should be budgeted at a higher price. This will allow you to plan for the necessary upgrades, from home insulation to new roof or HVAC investments.
Overall, your home will be more energy-efficient and save a bundle on electricity – both from using less and generating your own – but the initial cost will be higher. Return on investment calculations can help you see the total repay time in terms of lower power bills and increased property value.
Don’t forget the insurance implications and coverage for older roofs with solar. Upgrades can decrease your insurance costs, as well.
Overcoming the Challenges
To overcome the challenges of installing solar on an older Nevada home, first start with a thorough home assessment. Collaborate with historic preservation experts or HOA authorities (if necessary) to ensure a harmonious upgrade.
Explore advances in solar technology suitable for older homes, such as low-profile panels for less visibility and micro-inverters to accommodate partial shading. Be sure to make upgrade and energy efficiency plans as part of your solar projects for the best results.
Planning for Solar with Older Nevada Homes
Installing solar on older Nevada homes can be highly beneficial, as long as you understand the challenges and are prepared to face them. Understand the durability of your roof, the energy-efficiency of your home (and how to improve it) and the possible electrical requirements to be met. Tailor your approach for each individual older home. You can benefit from solar despite these challenges and come out with a much improved home with far lower power bills as a result.
