As long as the subpanel meets the 120% rule also (1.2 x bus rating greater than 45 + 40 main if you can find one.), that is fine. A 100A bus subpanel with a 50A or 75A main and three 15A feeds would be OK since the total is less than 120A.
I am trying to figure out how many panels to put in a string. I have 20 San Tan 250 W panels. (specs below) and a MPP Solar LV 6548V (specs below) How many should i put in series and what gague wire should I run 230ft. Unclear on # of conductors and Load Current amps. Is my calculation good...
Then divide that number by the amount of power that a solar panel outputs per day/night cycle. Initially my numbers were off because I thought solar panels put out 45,000 per cycle, but it''s actually 45,850 (give or take a kPs or two). That should give you the amount of solar panels you need to cover one day/night cycle of power.

To ensure the prospective manufacturer has included the correct solar panel sizing (i.e., their ALR calculation meets your project needs), there is a simple calculation you can do.
Your solar panel system must comply with building regulations in terms of structural integrity, electrical safety and fire safety. These regulations may vary depending on the size and type of the installation. It's advisable to work with accredited installers who are familiar with these requirements.
The aim is to boost the UK's solar usage considerably, greatly reducing the countries reliance on fossil fuels and allowing it to meet its proposed target of 70GW of solar power by at least the year 2035, as well as the global Net Zero goal by 2050. Here's what you need to know about the new government rule changes for solar panels.
However now that companies no longer need to apply for full planning permission if their panels generate more than 1 Megawatt of power, this removes a lot of the hurdles originally in place that both caused delays, and also prevented a lot of businesses from initially applying.
Current rules that require businesses to apply for planning permission if solar panels will generate more than one megawatt of electricity will also be scrapped, meaning organisations will be able to install more solar panels on rooftops without the delay and cost of applying for planning permission.
In March 2024, the European Parliament approved a law requiring solar panels on all new residential buildings by 2030. The EU Solar Standard makes it mandatory for member states to gradually include solar installations in new public, commercial, and residential buildings.
Solar panels aren't mandatory on new builds in the UK. However, other parts of the world have implemented requirements - in the EU, for example, solar panels will be mandatory on all new residential buildings by 2030.
