solar panel permitted development

Before you order your do-it-yourself home solar energy system and start building your own solar panels, you might want to save yourself a big headache (and several thousand dollars) by looking into your local zoning.  If you live on acreage in an unincorporated area, you might still be subject to some state restrictions.  So it is always wise do ask some questions and do some research at the beginning of your project’s planning process (instead of waiting until the money has been spent!).

In the United States, zoning restrictions usually are the least restrictive at the federal level, and become increasingly restrictive at the most local levels.  That means (usually), the state is less restrictive than the county; the county is less restrictive than the town or city; the town or city is less restrictive than the homeowners’ association.  So is you do your zoning research at the most restrictive level that applies to your situation, you should be in good shape.

If you live in a community that has a homeowner’sassociation, start there.  Find out if there are rules about installing solar panels (or any structures) on your roof, or if there are rules about the kind of roofing materials you can use.  It’s not the end of the world if your discover restrictions.  You’ll just have to develop a proposal that your association board will find so appeal that they’ll approve it with ease.

If your zoning comes from your town or city regulations, you’ll need to go the planning office and find out what your local zoning laws say about solar panel installations.  It may take you some time to find out exactly who to talk with; it may be the zoning department, or the planning department, or the building code department.  But once you uncover the proper authority, find out what permits you need, and what the process is that you’ll need to follow.  If there are no town or city zoning codes in place that cover solar panels, you’ll need to research at the next level.

The next zoning authority level is your county. If you can find the county website online, you may be able to get answers without having to visit the county offices in person.  Either way, though, you’ll need to find out which department handles zoning and permits, and get your answers there.  If the county has no zoning regarding solar panels, keep asking questions.  Someone at the county level should be able to tell you whether your state has any laws in place.

You can also approach all of this research by finding local solar equipment suppliers and installers.  Since the zoning regulations affect their businesses, they’ll usually know exactly what the laws are, if any.  Be sure you ask a reputable, licensed business person, though.  And double check their answers, don’t just rely on what they tell you.  As with any “home improvement” there are a lot of scams out there that are easy to avoid by doing a little research of your own.

pv of cash flows

Visual Basics Code for Future Value of uneven cash flow?

I have a program which user enters bunch of UNEVEN cash flows and I store them in an Array Index, then user enters the interest rate, finally the user selects the time at which the FV is calculated

Since it’s an uneven cash flow, I need to figure out FV for each cash flow then add all of them toger

Formula : FV= PV (1+i)^n
then add x number of cash flows together

Can someone please help with the codes? LIke how to code that and how to extract the info from the array index? THanks a BUNCH!!

It has been way too long since accounting but all of this seems eerily familiar. I wasn’t sure about the formula such as what value will be for i (interst rate?) and what will be for n (time?) but I took a stab at writing something up in VB.NET.

You will want to change the UnevenValues array to contain whatever values need to be in there, this is most likely coming from the user. The interestRate and fvTime will also need to be changed to whatever input values. Hopefully I was close on the formula but with the inputs you should be able to modify this code to get it to work for you.

‘FV= PV (1+i)^n
Dim UnevenValues As Double() = {1, 2, 3, 4, 5}
Dim interestRate As Double = 0.0525
Dim fvTime As Integer = 10

‘Get all of the Future Values
Dim fvValues(UnevenValues.Length – 1) As Double
For i As Integer = 0 To UnevenValues.Length – 1
fvValues(i) = UnevenValues(i) * ((1 + interestRate) ^ fvTime)
Next

‘Add the Future Values together
Dim total As Double = 0
For Each fval As Double In fvValues
total += fval
Next

MessageBox.Show(CStr(total))

Present Value 4 (and discounted cash flow)

solar panel outputs

Can a solar panel work with an inverter?

The inverter I am using gets the required 12 DC volts from the solar panel, but fo some reason it just won’t output the 110 AC voltage. When the inverter is hooked to a car battery, it works just fine off the same 12 DC rating. Help me out please…

Solar panels output a very small amount of current. Even though you’re getting 12V from the panels, you aren’t getting enough amperage to power even the inverter itself, let alone anything plugged into the inverter.

Car batteries are able to be used with inverters because they can crank out enough amps to power the inverter and whatever is plugged into it. Inverters only step up voltages and change DC to AC. They do not increase power (wattage) potential. If you want to plug in a 20W appliance into the inverter, the 12V source must be able to deliver 20W of power regardless of voltage.

In pretty much everything solar powered, the panels are used in conjunction with batteries. The solar panels slowly recharge the batteries. The batteries are where most of the power comes from. Nothing is driven directly from the solar panels themselves unless the power requirement is low enough, such as a calculator.

Solar panels will have an output rating in watts (W). If the wattage of your inverter plus whatever you plug into it is lower than the panel’s output rating, then it can power it directly, provided you have 100% light input into the panel.
