Slash Bills


Calculate calculate account

United States Energy Information Administration 2024 year February released statistical sample shows whole America residents average every month consume 899 kilowatt-hours of electricity quantity. According to the average per degree electricity $0.168 unit price, calculate one single detached house's basic electricity expenditure every 30 days, which reached $151.03. Summer July and August because of air conditioner high intensity running, single month electricity usage quantity usually will skyrocket 40% to 60% leading to electricity fee bill breaking through $230 peak value.

One set total installed capacity is 7.2 kilowatts household photovoltaic system, and at every year sunshine time reaches 2000 hours, an area can produce 25 to 30 degrees electricity on a single day. Single day 30 degrees electricity capacity output can offset a 4-person family daytime operate 1 unit 3-ton central air conditioner plus 2 units refrigerators produced 70% to 85% load consumption. When the external environment temperature reaches 35 degrees Celsius, time because of panel temperature coefficient, every rise of 1 degree Celsius will bring 0.35% power loss. The system that day's actual effective output can still be stable at 22 degrees electricity above.

l A 7.2 kilowatt system occupies a roof of about 400 square feet and contains 18 pieces. The single piece power is 400 watts monocrystalline silicon panels.

l 2000 hours annual average sunshine duration enough to let system at 12 months inside stably output 10,500 to 11,000 kilowatt-hours total electricity quantity.

l Ten thousand, five hundred degrees annual power generation quantity according to $0.168 billing unit price convert can at 365 days inside save $1,764 purchasing spend.

Sell go to grid

The whole of America currently has 38 states legislate a forcibly execute 1 to 1 net metering electricity price policy allowing individuals to 100% retail electricity price put extra electricity quantity input municipal public lines. Assume the system from noon 12 o'clock to afternoon 2 o'clock sunshine peak range every hour full load output 6 kilowatt-hours electrical energy. At 1 o'clock in the afternoon, the house's internal only has a router and a refrigerator running, and its actual power consumption does not reach 400 watts. The system will put the remaining 5.6 degrees of electricity automatically transmit back to the external lines and at the smart electricity meter on produce 5.6 kilowatt-hours single day credit quota.

Arrived at 8 o'clock because of panel power generation power drops to 0 watts house starts from external lines extract daytime stored 5.6 degrees electricity quota. At a 30-day billing cycle, if daytime total transmitted 300 degrees electricity and evening extracted 280 degrees electricity, the month-end electricity quantity settlement bill on net consume quantity will display as negative 20 degrees. Public utility company will put 20 degrees positive energy balance roll into next natural month offset future expected $0.168/degree electricity purchasing spend.

l Thirty-eight states net metering regulations require public utility companies to use 12 months as one billing cycle to calculate full year electricity usage positive negative deviation value.

l Three hundred degrees electricity single month transmission quantity at $0.168 unit price equals to towards grid deposited $50.4 credit asset.

l 0 watts night power generation state under house average every hour still needs consume 0.8 to 1.2 kilowatt-hours basic standby electrical energy.

Hide away high price

Time-of-use electricity price billing model currently covers 15% of residential users and puts every day afternoon 4 o'clock to evening 9 o'clock as per degree electricity as high as $0.45 unit price range. From morning 8 o'clock to afternoon 3 o'clock, the low load time period, the same power company charges a standard sharply drops to per degree electricity $0.12 forms 275% price deviation. Facing west or facing south, install tilt angle at 20 degrees to 30 degrees between panel array can ensure afternoon 4 o'clock to 6 o'clock high price range inside maintain 30% to 40% rated power output.

Match with one unit depth of discharge reaches 90% 13.5 kilowatt-hour household energy storage cell can let users at every day afternoon 4 o'clock cut off external circuit power supply. The system automatically releases cell internal 12 degrees electricity to support oven and dishwasher etc. high energy consuming appliances running 3 to 5 hours. Adopting a 5-hour stagger peak discharge strategy makes users at 365 days inside the highest price electricity fee expenditure infinitely approaches $0.

l $0.45 peak unit price compared to the whole America $0.168 average price presented 167% price upward float ratio.

l The 13.5 kilowatt-hour cell pack can bear continuous power of 5,000 watts as well as peak power of 7,000 watts appliance load impact.

l 90% depth of discharge index cell at retain 1.35 degrees electricity bottom layer capacity under can continuously loop run exceeding 6000 times.

Lock dead unit price

According to the 3% inflation rate, calculate the current $150 bill at 15 years from now will inflate to every month $233 and at 25 years from now reach every month $314 extreme value. Purchase and full payment hold one set total construction price is $25,000 8 kilowatts photovoltaic equipment equals to put future 25 years expected produced 240,000 degrees electricity purchasing spend one time pay clear. Apportioned to every one degree, the electricity levelized cost of energy is forcibly locked at $0.06 to $0.08 fixed deviation range inside.

Compare public utility company $0.168 initial quote from system grid-connected power generation 1st day start per degree electricity purchasing unit price just obtained 52% downward adjust amplitude. In up to 25 years, equipment warranty cycle inside unit price difference can cumulative produce $35,000 to $45,000 absolute cash flow surplus.

l 2.5% to 3% annual average electricity price rise amplitude at compound interest calculation model under will let 25 years after total electricity usage expense increase nearly 110%.

l Two hundred and forty thousand degrees electricity 25 years total expected yield established at panel every year maintain 0.5% constant degradation rate engineering parameter on.

l $0.06 levelized cost of energy lower than the whole America 50 states inside any one traditional public power supplier lowest tiered quote.

When return capital

Take one set before discount marked price is $22,000 7 kilowatts standard residential equipment as an example, deduct $6,600 federal post-tax subsidy actual sunk spend will drop to $15,400. The first-year running system is able to produce 10,000 kilowatt-hours of electrical power according to the per degree electricity $0.18 average electricity price. Calculate that year's intercepted $1,800 loss.

Put $15,400 net initial investment divided by every year's $1,800 cash return flow obtained basic investment payback period is 8.55 years. Introduce every year a 3% electricity price rise probability curve after 5th year electricity fee save amount rises to $2,080 and 10th year reaches $2,411. Put year by year increasing compound interest revenue substitute into dynamic calculation model inside actual investment return capital critical point is in advance compressed to 6.8 to 7.2 years between.

l $22,000 7 kilowatt system unit price converts to per watt installation cost is $3.14 conforms to 2024 year first quarter industry median standard.

l $6,600 30% tax credit amount allows user at 1 tax year to take full amount write-off or carry forward to subsequent 5 tax declaration cycles.

l 7.2 years return capital cycle at equipment remaining 17.8 years warranty period inside produced all 178,000 degrees electricity acquisition cost is $0.

Valuation how calculate

The American Society of Appraisers promoted one set named PV Value discounted cash flow algorithm model to calculate photovoltaic hardware remaining life cycle residual value. This algorithm does not purely rely on hardware purchase invoices but calculates panel at future 15 to 20 years inside can produce actual per degree electricity economic benefit. Model input parameters contain every year 0.5% module degradation rate as well as local public utility company average every year 3.1% electricity price upward adjustment inflation expectation.

Take one set run 5 years and initial conversion efficiency is 21.5%. System as an example, its current actual output power still maintains at initial factory specification 97.5%. Appraiser put system remaining 20 years expected produced 185,000 degrees electricity according to $0.18 baseline unit price convert into future revenue flow.

Through applying a 6.5% discount rate, future $33,300 electricity fee savings convert into current net present value. When the external environment temperature reaches 40 degrees Celsius, the time model will automatically introduce a negative 0.28%/C temperature coefficient to correct the midsummer season yield deviation.

Exempt pay property tax

Assume the owner for one single market value is $400,000 property added construction price is $30,000 10 kilowatts solar energy array. According to New York state, certain counties and cities have a comprehensive property tax rate as high as 2.2%. A $30,000 asset value increase originally should trigger an extra $660 tax burden every year. 100% solar energy property tax exemption policy forcibly put this $30,000 from the tax bureau annual tax calculation base inside completely strip out go. At system set 25 years physical life cycle inside $660 single year tax exemption amount cumulative for owner intercepted $16,500 implicit legal obligation expenditure.

Buyout system ownership owner completely occupies whole line tax exemption bonus curve and adopting power purchase agreement lease model resident then faces $0 asset value increase audit. Lease contract inside equipment ownership belongs to third party financial institution leads to house at list sell time unable to trigger above text mentioned 4.1% premium transaction model. Handle lease contract transfer procedure needs to consume up to 14 to 30 days credit background investigation cycle extreme big probability will pull low house transfer circulation rate.
