Going Solar: Everything You Need to Know

Can you live off solar power alone? The answer is yes, but going off-grid requires a big financial and time commitment. Using the sun to power your home can have numerous benefits such as lower energy costs and living a more environmentally-friendly lifestyle, but it’s important to understand the requirements and know what equipment is needed.

Examples of Homes Powered by Solar Power

Solar power is becoming more and more common in homes across the country. One example of this is in the village of Urbasa, in the Basque region of northern Spain. All 558 homes in the village run on 100% renewable energy and the power is provided by an on-site solar panel system. Another example is the town of Cordova, New Mexico. The city recently announced it has purchased four solar energy systems to power their local government facilities and schools. These examples demonstrate how solar can be a reliable source for powering homes.

The Benefits of Going Solar

Going solar has significant benefits, and here are some of the main ones:

Cost Savings

The cost of electricity is increasing, but with a solar system installed in your home, you can significantly reduce your energy bills and utilities. Depending on the size of the system, you could be saving up to 50-90% of your energy costs.


Unlike traditional energy sources, solar energy is clean and abundant, meaning it’s much better for the environment. Solar systems reduce reliance on fossil fuels, resulting in lower emissions and a smaller carbon footprint.

Energy Independence

A solar panel system is a great way to increase energy independence. This can be especially useful if you live in an area with unreliable or higher-cost electricity services.

Requirements of Going Solar

Installing a solar system in your home will require a financial and time commitment. Before committing to going solar, it’s important to consider the initial cost, ongoing maintenance, and many other factors.

Initial Cost

The cost of a solar system depends on many factors, such as its size and the type of equipment used. Generally, you should expect to pay between $10,000 and $30,000. It’s important to note that the cost can be covered through a loan or by using a solar lease or power purchase agreement.

Time and Energy Investment

Installing a solar system requires a lot of planning and preparation. The process can take several months, depending on the size of the system. Additionally, you’ll need to factor in a substantial amount of energy and time to maintain and repair your system.

How to Calculate Solar Energy Requirements

In order to calculate how many solar panels you need for your home, you need to consider your year-round energy needs. To determine those, you’ll need to understand your monthly energy usage and consider additional factors like the size of your home, the climate, and local ordinances.

Year-Round Solar Energy Needs

It’s important to understand the amount of energy you need to produce on a daily basis. This is called your monthly energy usage, and you can calculate this by looking at your energy bills or using an online energy usage calculator.

Factors to Consider when Calculating Needs

When calculating your energy needs, there are several other factors to consider. These include the type of home you live in, the climate in your area, and additional appliances and devices you may use.

Sizing Solar Panel Battery

When calculating your energy needs, you should also consider the size of your solar panel battery. A solar panel battery stores the energy generated by your solar panels and allows you to use it at other times when the sun isn’t shining. The size of the battery depends on how much energy you need to produce and store.

Finding the Right Solar Panel System

When it comes to finding the right solar panel system for your home, there are several things to consider.

Equipment Needed for a Solar System

In order to run a solar system, you’ll need the right equipment. This includes solar panels, an inverter, batteries, a charge controller, and wiring.

Selecting the Right Type of Panel

The type of solar panel you choose will depend on a variety of factors, such as your budget and the size of your home. There are two main types of solar panels: monocrystalline and polycrystalline. Monocrystalline panels are more expensive but have higher efficiency and greater durability.

Selecting the Right Installer

It’s important to find a qualified installer with experience in installing solar panels. You should research local companies and read reviews to make sure you’re working with a reputable and reliable installer.

Challenges of Going Solar

Going solar can have many benefits, but there are also some challenges to consider.

Maintenance and Repairs

A solar system requires regular maintenance and repairs, which can be costly. You’ll need to factor in the cost of regular inspections, cleaning and replacement of parts periodically.

Cost of Energy Storage

Storing energy can be expensive, depending on the size of your system. The bigger your solar system, the bigger and more expensive the battery will be.

Limited Energy Production in Bad Weather

It’s important to note that solar panels don’t produce much energy on cloudy or rainy days. Therefore, you may need to consider other sources of energy for these days.


Going solar has numerous benefits, from financial savings to living a more environmentally-friendly lifestyle. However, it’s important to understand the necessary requirements of going solar, such as financial commitment, initial cost, and time and energy investment. Calculating your energy needs and finding the right system and equipment for your home is also essential. Additionally, it’s important to consider the challenges of going solar, such as maintenance and repairs, cost of energy storage, and limited energy production in bad weather.

If you’re considering going solar, ask yourself: Can you live off solar power alone?. Consider the requirements and challenges of going solar, as well as how to size your solar panel battery and find the right system for your home. With a financial and time commitment, going solar can help you save money, reduce your carbon footprint, and become energy independent.
