The best times to add solar panels to an existing solar system
(1) Many people are already using photovoltaic power now, but as economic conditions change, households are gradually adding new electric devices such as electric cars and heat pumps. Some home appliances have also been upgraded, causing electricity bills to increase, and people are gradually moving toward the era of whole-house gas and electricity. The current solar system cannot supply such a large amount of electricity, then at this time we have to consider adding solar panels to the existing solar system.
(2) Currently, the cost of electricity is on the rise, and for most families, there is even a pressure to use electricity. The use of new solar panels can reduce energy costs. Although, you need to spend a certain amount of money when you first install it, it pays for itself in about 3 to 5 years, which makes it very affordable when you look at it.
(3) It is really recommended for families who have spare installation space and for those who do not have the financial burden at the time of the initial installation, even if they do not use it now, they will use it in the future.
How much does it cost to add solar panels to an existing solar system?
(1) The price of adding solar panels: about $0.10 per watt, or about $40 per panel (assuming 400 watts solar panel).
(2) One point that is often important to note is that the cost per watt is higher for smaller projects than larger ones Why? That’s because whether many solar panels are installed or fewer, there are overhead and labor costs. Regardless of the project, workers should be paid accordingly, so smaller projects are more expensive.
(3) Replacing or installing solar panels also incurs additional costs: if you want to replace old, degraded solar panels on your roof, you will have to pay for the corresponding labor costs, and you usually can’t reuse the old parts, which also need to be replaced. If you want to mix and match old panels with new panels to make a unit, you’ll still need to replace the old wiring and other parts, too.
(4) Adding solar panels to an existing system can often qualify for new energy incentives, mainly to promote renewable energy, and many countries often offer subsidies (flat rate payments, tax credits or rebates) or rewards.
Considerations for adding solar panels to an existing solar system:
1. incentives in your area may have changed.
It may be that your area has eliminated its pro-solar policies, but at this point in time, this will not be the case in most areas.
2.You need to determine if you have the right roof space for solar installation.
For example, if you have used up the most efficient space for your first solar installation, and now you can only install solar panels facing north, it will result in solar panels facing the opposite side of the sun, which is not conducive to absorbing full sunlight and will affect their efficiency in generating electricity.
Remedial program:
2.1 Ground mounting.
2.2 Completely replace old solar panels with new energy panels. New energy panels can save up to 25% of electricity in the same roof space compared to old panels. (But too wasteful and not recommended)
3. Is your utility grid company accept it?
When you add solar panels to an existing system, the utility grid company can force you to adopt new incentives for the entire solar panel fleet. (or at least the panels and grid connected to the new energy panels)
4. Whether you can find someone willing to install them?
It is often advisable to find the person who installed your solar panels for the first time so that the handover of which is not overly cumbersome, as most people don’t want to carry out their own work in a program that someone else has worked on. It’s important to note that solar contractors who take on the task of expanding new solar panels will usually bypass the old system rather than tweak it. Of course, they won’t take on warranty responsibility for the old panels.
Experience has found that for homes in desperate need of electricity, installing new solar cells on an existing solar system can still be of great benefit. Not only will it supply our power needs, but it will save us a lot of money on our electricity bills in the long run. When all of the above concerns and needs feel good to you, or if you feel that new energy power is important for your home electricity needs, then this will be a solid deal for you.
