Residential Solar: Factors To Consider When Using Solar To Fully Power a House

While solar power can indeed meet a substantial portion, or in fact, all of a household’s energy requirements, several factors need to be considered when exploring options for solar power in your home.

  • Energy Consumption: Begin by assessing your household’s energy consumption. Analyze your past electricity bills to determine your average daily and monthly energy usage. Understanding your energy needs is the foundation for sizing a solar panel system accurately.
  • Sunlight Availability & Location: The amount of sunlight your location receives is a pivotal factor. Areas with more sunshine, such as regions closer to the equator, are better suited for solar power. However, even in less sunny regions, solar can still be a viable option, albeit with potentially larger solar panel arrays.
  • Panel Efficiency: The efficiency of solar panels matters. More efficient panels can generate more electricity from the same amount of sunlight. Consider the type and quality of panels you intend to install.
  • Roof Space: Assess the available roof space for solar panel installation. The size of your roof will impact the number of panels you can install and their orientation for optimal sunlight exposure.
  • Budget and Financial Incentives: Evaluate your budget for solar installation. Explore available financial incentives, such as tax credits, rebates, and net metering programs, which can significantly offset initial costs.

These factors will influence the feasibility of installing solar at your home. They will also help you decide whether or not you can use solar to fully power your home. For more help on working out your own panel requirements, click here.

The Balance Between Consumption & Production

Understanding and achieving a delicate balance between energy generation and consumption is paramount before determining if solar power can fully power a house. This equilibrium hinges on matching the intermittent nature of solar energy production with the continuous energy demands of a household. By comprehending their energy consumption patterns, homeowners can size their solar panel systems and energy storage solutions appropriately.

Oversized systems may lead to excess energy generation, which, without efficient storage or utilization, can go to waste. Conversely, undersized systems may leave households reliant on the grid during periods of low solar output. Striking this balance not only ensures efficient use of solar resources but also influences the economic viability and sustainability of a solar-powered household, making it a fundamental consideration in the transition to solar energy.

The Crucial Role of Energy Storage

Energy storage, like a battery, is crucial for fully powering a house with solar because it addresses the fundamental challenge of matching the intermittent nature of solar power generation with the continuous energy demands of a household. Solar panels generate electricity primarily during daylight hours when the sun is shining. However, homes require power around the clock.

Energy storage, usually in the form of batteries, serves as a buffer, allowing excess daytime solar energy to be stored for use during evenings, nights, and cloudy days. This ensures a consistent and reliable power supply. It also reduces reliance on the grid, maximizes self-consumption of solar energy, and contributes to cost savings and environmental sustainability. Without energy storage, fully powering a house with solar alone becomes impractical and less dependable. In fact, according to SEIA (Solar Energy Industries Association), by 2027, nearly 30% of all new behind-the-meter solar systems will be paired with storage, compared to under 10% in 2022.
