What are the 2 main disadvantages to solar energy?
The two main disadvantages of solar energy are cost and the dependency on weather conditions. Solar panels are expensive to install and maintain, making it difficult for many people to benefit from the energy source.
Additionally, solar energy is associated with the availability of sunlight, meaning regions with heavy cloud cover and limited sun exposure will not receive as much energy from their solar panel array.
This can reduce the efficiency of solar energy usage as insufficient energy may not be generated in certain seasons. Additionally, in order to maximize efficiency, one must often consider the angle of the sun, the location of their solar panels, the area of the solar panels, and the amount of shade that is present in the surrounding area.
All of these factors can affect the cost of the installation and the efficiency of the energy collected.
Will a 10kW solar system run a house?
Yes, a 10kW solar system can run a house. The amount of energy produced by a solar system depends on several factors, including the size of the system, the geographic location, the tilt of the panels and the amount of sunlight your area receives.
With this in mind, a 10kW solar system will produce an average of about 30-40 kWh of energy per day. This would be sufficient to cover the average household’s electricity consumption. A typical household with four occupants will use between 10-15kWh per day, so a 10kW solar system would comfortably cover this.
However, if you have a larger household, a higher energy consumption rate or limited roof space, a larger system may be required. It is always best to speak to a professional who can assess your energy needs and recommend the right system for you.
How big of a solar system do I need to go off grid?
The size of solar system needed to go off grid largely depends on several factors, such as the amount of energy that you currently consume, the type of system you select and the geographical characteristics of the location.
Typically, the size of system for an off grid home is about five kW for a 1,000 square foot home. It is recommended that you perform an energy audit of your home and calculate your current electricity needs.
This will help you explore what type of solar system may be suitable and help you understand the size of the system you will need.
You could opt for an all-in-one pre-fabricated kit, which includes all the components of the solar system. This is beneficial as the system is ready to go on installation and includes most components necessary.
Alternatively, you could opt for a customized system, which typically allows for more flexibility and better control over components, but may require more research and planning.
Other factors to consider include the geographic location, such as the amount of sunlight the home receives and the type of terrain, as mountain ridges may cause some shading and therefore, impact the solar system’s efficiency.
The design and orientation of rooftops and the size of the solar array will also influence the size of your solar system and the energy output.
Finally, you also need to take into account any additional costs and technical configurations. The cost of components such as batteries and other electrical components can be considerable and should be factored into the overall costs of going off grid.
The technical configurations, such as the details of the inverter and other electrical components are all necessary and should be chosen carefully, as they will impact the performance of the system.
In summary, the size of solar system you need to go off grid depends on many factors, such as your current energy consumption and the geographic location, as well as any additional costs and configurations.
It is suggested that you factor in all of these elements and perform an energy audit to calculate your system size before investing in a solar system for your off grid home.

How long do solar panels last?
Solar panels have an expected life of 25 to 30 years, but in many cases they can last even longer. The exact lifespan of solar panels depends on the type of system and how well it is maintained. Generally speaking, crystalline silicon panels tend to last longer than thin film panels.
With proper maintenance and cleaning, they can easily last beyond the manufacturer’s recommended 25 to 30 year lifespan. However, the amount of available energy that solar panels can produce gradually declines over time so even with proper maintenance and care, you may notice a decrease in the amount of energy produced by your solar panels as the years go by.
Factors that may affect the lifespan of solar panels include: exposure to the elements, exposure to dust, exposure to snow and extreme temperatures, and any damage caused by fallen objects or debris.
For maximum lifespan, solar panels should be inspected regularly and cleaning should be done every few months if needed.
Are solar panels hail proof?
Solar panels are not “hail proof” in the sense that hail, like any other physical force, can cause damage to solar panels if it is of a large enough size and has enough force behind it. However, solar panel manufacturers use polymers and chemical coatings to protect their products from hail, though they cannot guarantee they will be “hail proof”, since that would imply that no hail would ever be able to cause any damage to the solar panel.
Solar panel manufacturers test the panels to determine which materials and coatings are best suited for protecting them from hail, which in most cases, does a good job of protecting the panels from hail that occurs during ordinary storm systems.
Additionally, many manufacturers now offer warranties specifically for hail damage, so customers can purchase additional protection should hail damage occur.
Does hail damage solar panels?
Yes, hail damage can affect solar panels and cause serious damage. Hail can cause cracks in the solar cells that make up the individual solar panel panels. This can significantly reduce the efficiency of the device, or even disable it entirely, leading to a need for costly repairs or replacements.
The size, weight and speed of the hail can affect the severity of the damage, with larger, faster moving hail causing more severe damage than smaller, slower moving hail. It is important to know that not all solar panels are made to withstand hail, so be sure to research your specific panels and their levels of hail protection before installation.
In some areas, solar panel owner may want to get hail insurance, as hail-damaged solar panels can be costly.
Can we run off-grid solar system without battery?
Yes, it is possible to run an off-grid solar system without a battery. This is accomplished through a concept known as net metering. Net metering involves connecting the solar panels to a utility meter that is used to measure the solar power generated.
This power is then sold back to the utility for a credit on the customer’s utility bill. In this way, the solar power generated during the day can offset the power used at night and other times where the solar system is not producing any power.
Additionally, some utilities may also pay the customer for any excess solar power generated during peak production times. This allows customers to remain off grid and still save money.
Can I have solar without connecting to the grid?
Yes, it is possible to have solar without connecting to the grid. This is known as off-grid or stand-alone solar, and it requires special components such as batteries to store the energy generated and inverters to convert the DC electricity from the solar panels into usable AC electricity.
With off-grid solar, your home is completely independent from the local utility and you will no longer receive a power bill. However, it comes with certain challenges, such as limited energy sources, the cost of the batteries, and day-to-day management of the energy usage.
But overall, it is an increasingly popular option for those seeking greater energy independence and reduced energy costs.
