With households throughout the country battling ever-rising electricity bills, the demand for sustainable alternatives to traditional grid power has never been stronger. Energy bills are at the breaking point dragging the monthly budget through the roof with utility costs doubling over the past few years for many families. Solar panels have quickly become a popular solution to this increasing financial pressure, leading the way to a dramatic drop in your energy bills and less reliance on older, expensive energy grids.
It is not just about monthly household costs — the burden of expensive energy bills is a long-term financial drain on household stability and property values. Although solar has come a long way, the vast majority of homeowners are turned off by the hassle of going solar. It’s a big decision for sure — understanding the energy that you specifically need, and figuring out a solar outfit that best fits your home should be your first steps in this journey.
In it, we’ll go over the process you need to follow to create this system with a link to our free spreadsheet that does the math for you. And by the time you’re finished, you’ll have a straightforward path to deciding if solar panel installation is right for you based on your energy requirements, budget, and home ownership situation.
Understanding Your Home’s Energy Consumption
The long and short of it is that before you drop money on solar, you should get a full energy audit of your home, especially if you have energy-efficient appliances. Begin by gathering the utility statements of the last twelve months, so you can pinpoint seasonal trends and peak usage. For example, understanding how your household compares to average laredo electricity rates can give you a better benchmark for potential solar savings. Many utilities offer access to in-depth consumption statistics on online account pages, with the ability to view hourly or daily usage patterns that might point to opportunities for efficiency upgrades.
For even more comprehensive background on just how you’re using energy in your home, you might want to have a home energy monitor installed. These plug into your electrical panel and monitor per-appliance use on the fly. HVAC systems, water heaters and refrigerators are usually the biggest power suckers. Knowing how much they use will allow you to work out how big your solar system needs to be.
Find your total energy needs by adding the amount of kilowatt-hour (kWh) usage you have used in all months per season. The average American household uses 877 kWh per month of electricity, but that average varies widely depending on factors such as house size and climate. Consider any future changes, including electric vehicles and new appliances, as they will affect your future energy needs. This in-depth review paves the way for a solar power system that is right for your home.
The Science Behind Solar Panels: Photovoltaic Effect Explained
Solar panels work by capturing energy using the photovoltaic process — sunlight is absorbed by semiconducting materials such as silicon, which creates an electrical current. When photons strike the surface of the panel, they excite electrons in the silicon cells and form an electric field that causes current to flow. This fundamental transformation takes place in several layers of advanced materials that work together to capture and convert the sunlight into energy.
A full solar power installation is comprised of different components all of which work together. The panels are used as the visible top layer of the system, and are either microinverters or string inverters that convert the produced DC power to AC power. And there are battery options now for many systems, so that even after the sun goes down or if a cloud goes by, you can continue to use the stored energy, and keep track of how much energy you are producing through real-time monitoring systems.
Actual solar panel efficiency in the field varies according to environmental factors. The amount of power produced depends directly on how many solar modules are receiving sunlight and the sun’s intensity. Weather patterns, seasons and the location all have an effect on how much energy production is running. Nearly all residential installations during the day peak at 4-6 hours output, and that’s where components are based so it’s the design of the systems to accommodate that variation.
Choosing the Right Solar Panels: Monocrystalline and Beyond
Comparing Panel Technologies
Monocrystalline solar panels are considered the most efficient in residential technology, boasting a rate of 15-22% efficiency and requiring less space on the roof. These panels are made of single-crystal silicon, which makes them built to last in any condition, even low-light conditions and high temperatures. What attracts most in them is their black, shiny look and considerable slimness, which makes them perfect if you want to see your speaker.
Selection Criteria for Homeowners
When comparing solar panels, roof space will be a major consideration. High efficiency monocrystalline panels are ideal for homes with limited roof space since they produce more power per square foot than other panels, although more expensive from the get-go. Whereas larger roof dimensions are in question, polycrystalline panels can be the most profitable solution that is usually functioning at 13-17% efficacy. Consider local climate – panels with lower temperature coefficients are better for hot climates, while those with improved low-light performance are better suited to cloudy regions.
Manufacturer quality and warranty policies are a large factor in long term reliability. Look for equipment with a minimum 25-year performance warranty and degradation rates of less than 0.5% per year. High-end manufacturers offer at least 90% output for 25 years or more, leading to consistent energy generation over the course of the system’s life. Finally, before you choose, you should also take into account the financial health of the company behind the product, and its history of honoring claims on warranties.
Calculating Your Solar Panel Requirements
Transforming your home’s electricity usage into a viable solar panel system requires a logical process. Start with how much electricity you consume in kilowatt-hours on average each day, which can be found on your utility bills. Divide how much you consume a month by 30 to find your daily requirement. If you consume 900 kWh per month, for instance, you will need about 30 kWh per day.
Then account for the number of hours per day your location receives full sun and loses efficiency. The majority of areas will have 4-6 hours of maximum sunlight per day, and system inefficiencies due to wiring resistance, inverter efficiency and temperatures will lower the sun-hours conversion by 20-25%. To accommodate these variables you can divide your average daily energy needs by the total peak hours of sun and your system efficiency. If you require 30 kWh per day and you have 5 peak sun hours and 75% system efficiency, then you need an 8 kW solar system operating under STC.
Calculate how many panels you need by dividing the size of your system by the rated wattage of each panel. Today’s household panels are usually between 350-400 watts. With an 8 kW system and 375-watt panels, you’d need around 22 panels. Factor in the amount of roof able to be used (minus any setbacks, vents and chimneys). Most home panels are around 17 square feet each, so make sure your roof will be able to accommodate how many you’ve calculated need to be installed.
There are a few web-based solar calculators you can use to double-check your math, but be careful: they vary in effectiveness. If you prefer the most accurate results, professional solar analysis is best; it includes specific shade analysis and site conditions. They use this software to model the solar potential of your roof and suggest good places for you to put your panels so you can maximize your solar production year-round.
Implementation Guide: From Planning to Activation
Financial Planning
The economic picture for solar installation has continued to improve through incentive programs. The current federal solar tax credit allows you to deduct 30% of the cost of installing a solar energy system from your federal taxes. Most states provide further tax credits, rebates, and SRECs which can offset the cost substantially. Find what your state offers by researching state programs through the Database of State Incentives for Renewables & Efficiency, to get the most benefit for your needs.
Installation Process
Start your installation process by getting quotes from at least three licensed residential solar installers. Find installers who are certified by the North American Board of Certified Energy Practitioners (NABCEP) and make sure they have adequate insurance and proper local licensing. For backup power that can be depended on during installation or grid outages, many homeowners choose portable power stations, like those from the company EcoFlow, which can keep essential appliances running while the grid is being switched. Installation usually takes 2-3 months from the time we visit a site until it’s up and running. This encompasses review by an engineer (1-2 weeks), getting the permit (2-4 weeks), the installation itself (2-3 days), along with final inspection and hook-up (2-3 weeks). The majority of installers will deal with all of the permitting paperwork and utility interconnection agreements, although homeowner associations may also have to sign off on the work. Experience little to no disruption to your routine, including installation, where most reroofs take a few days of work with the roofing, then electrical and testing.
