投资太阳能

想知道投资太阳能是什么样子吗?

客户投资太阳能有各种各样的原因, but if you’re interested in when you might recover your investment, you should be aware of possible changes that may impact your payback. Your investment will likely take longer to recover due to anticipated changes to how hg8868皇冠下载 credits customers for excess energy sent back to the grid and the value of that credit. If you make a solar investment looking only at the current compensation structure, 你不可能有一个准确的回报估计.

为什么事情会发生变化?

hg8868皇冠下载 is requesting changes to its on-site generation offering that are a step toward ensuring fair prices for all customers. hg8868皇冠下载 is seeking approval of a compensation structure that accurately measures an on-site generator’s use of the electrical grid, and an excess export energy credit rate that will result in a fair and accurate valuation of customers’ exported energy. 对于所有使用非遗留系统的客户, hg8868皇冠下载 is asking the IPUC to implement changes starting January 1, 2024, 包括:

  • 从每月净账单到实时净账单的变化, which would better measure customers’ actual reliance on the electrical grid.
  • A change in the excess exported energy credit from a kilowatt-hour (kWh) credit, 对住宅用户来说,价值约为10美分, to a time differentiated financial bill credit ranging from approximately 5 to 20 cents per kWh, 这将每年更新一次.
  • A modification in the eligibility size cap for commercial, industrial, and irrigation customers.

未来的更改将适用于谁?

The IPUC determined that any future changes will impact customers interconnecting a new or expanded system after Dec. 20, 2019, for residential and small commercial customers and after Dec. 1, 2020, for large commercial, industrial and irrigation customers.

可能的变化如何影响回报?

The example below shows a customer who uses an average amount of energy per year and installs a standard system with a life of 30 years. This customer would see a simple payback period of 13-17 years under the current compensation structure if they pay cash for the system. 然而, that payback period increases to 19-24 years for that same customer with net billing and a lower excess energy credit rate. If the system is financed, the simple payback period extends further. If the investment is evaluated using a discounted payback method, which is more accurate for evaluating the financial value of a project, it may not pay back over the life of the system regardless of whether it is financed or paid for in cash.

Example for using solar on-site generation to match about 75% of a home’s energy use under current and proposed future compensation structures.

The estimates and assumptions used in the payback scenarios are generalizations. 你的实际回报将根据你的能源需求而有所不同, 太阳能系统的大小和成本, 贷款利率, 税收抵免资格, 以及皇冠现金盘公司薪酬结构的任何变化. You can view your monthly and annual energy needs on hg8868皇冠下载’s 我的账户. 对于太阳能的个性化估计,爱达荷州电力公司建议 寻找专业安装人员 并得到多方出价.

The payback scenarios shown above used the following inputs:

  • 家庭能源使用:11,350 kWh per year (~950 kWh per month) with energy use highest in winter and summer for heating and cooling.
  • 太阳能光伏系统尺寸:6千瓦DC solar array (a common size for hg8868皇冠下载 customers) in Boise. Production based on representative residential customer generation customer bills and compared to estimates from National Renewable 能源 Laboratory’s (NREL) 光伏瓦计算器,使用计算器的默认设置.
  • 系统成本:3美元.00 to $4.每瓦00美元的NREL S. 太阳能 Photovoltaic System and 能源 Storage Cost Benchmarks, 最低可持续价格分析:2022年第一季度.gov) The cost for the example 6 kW solar system is $18,000 before tax credits and deductions.
  • Tax credits: 30% federal tax credit and full Idaho state tax deduction.
  • 能源成本:爱达荷州电力公司的定价 表1 (residential service) with seasonal tiered rates from approximately 8 to 12¢/kWh, 平均千瓦时成本约为10美分.
  • Utility bill increases: 1% per year based on hg8868皇冠下载’s energy fuel costs as noted in the current 综合资源计划(IRP).
  • 贷款详情:6年期贷款.6%的利率. 来源:谷歌项目天窗. 第一年实现的信贷.
  • 贴现率(要求收益率):4.5%. 这种输入应该基于个人需求. 在决定所需的回报率时, 至少, consider inflation and your 贷款利率 to make sure you break even. Decide what is the best use of your money right now by comparing the expected returns from different investment options, 像股票一样, 债券, 其他购买或只是为你的未来储蓄.
  • 超额能源信用值: Time differentiated credit rate of 5-20¢/kWh for excess energy delivered to grid as proposed in case IPC-E-23-14.

在线太阳能估算器,如谷歌 项目天窗, are available to help customize system cost estimates and payback timeframes. 然而, these estimates are based on the current compensation structure and do not account for the changes being pursued with the Idaho Public Utilities Commission that would likely lengthen payback periods.
