Solar is a long-term investment. 经验丰富的太阳能安装人员应该能够根据安装的大小估计投资回报, sun exposure and other factors. If you’re looking to save money on your electricity bill immediately, there are other low and no-cost options. 点击这里了解更多.

If you’re not sure if you’re ready to install your own solar, but you’re still interested in supporting renewable energy, you may be eligible for one of our other renewable energy programs, like 绿色能源 or 太阳能的选择, which do not require any equipment to install or maintain to participate.

If your property is heavily shaded, 太阳能电池板将需要更长的时间来获得回报，而不是在无限制阳光照射的地区. 太阳能电池板在朝南(东、西或两者结合)时表现最好, too) and are unshaded between 10 a.m. 和3 p.m. 一年到头. 网上有一些资源可以帮助你确定你的房子平均日照时间.

Your solar installation will be shaped by a variety of factors, including your budget, roof space and energy use. 安装通常以千瓦(kW)为单位，即系统的功率容量. An experienced installer should include in your bid the total project cost, 每千瓦的成本和系统的预期年能源输出基于您的网站的分析. 平均, 1 kW of solar power in the Puget Sound region can produce about 1,100 kilowatt hours (kWh) annually. 净计量允许您使用您产生的能源来抵消其他时间从电网使用的能源成本. 净计量并不提供任何经济利益，以确定太阳能系统产生更多的能源比你每年使用的基础上.

Consider other energy efficiency upgrades first. 你的用电量越低，你在太阳能设备上的投资就越少. 如果你想在不久的将来在家里添置一辆电动汽车或其他大型电器, factor that into the sizing of your solar array. If you need to replace your electrical panel to accommodate solar, 一个合格的太阳能安装商将审查这些选项，并可能将其纳入他们的投标. 如果你的屋顶不是很新，你可能会考虑在安装太阳能之前更换它. 安装完成后, solar panels should last more than 20 years, so any needed roof work should happen before installation.

Start by selecting an experienced installer. 通过PSE Recommended Energy Professionals (代表), 你可以找到一个可靠的和合格的太阳能安装可以帮助确定如果你的家庭或企业是理想的太阳能. 我们REP网络中的太阳能安装商客户满意度高，沟通及时. When considering solar, don’t feel pressured to sign anything before you fully understand the details and cost; be wary of aggressive sales and marketing tactics promising “free” or “no-cost” solar. 我们强烈建议对您的太阳能项目进行至少三个投标并检查参考资料.

Yes, the Federal Investment Tax Credit may apply to your solar installation. 《十大彩票平台》将商业和十大彩票平台项目的投资税收抵免从26%提高到30%. 这包括2022年安装的系统，并将在2032年底之前可用. Find more information here.

许多太阳能安装商可以帮助你通过当地的信用合作社或其他金融机构获得融资，并解释这对成本的影响, benefits and estimated return on investment from your installation.

Through net metering, PSE跟踪您使用的能源和系统产生的多余电量. The renewable energy sent back to the grid is credited against your usage. 您只需支付PSE提供的净电量，再加上您的基本每月费用. If you produce more energy than you use within a given bill period, PSE banks the extra net metering credit. 你的银行存款将在未来的账单期内自动抵消能源费用. Per state law, banked net metering credits expire March 31 of each year. 这就是为什么我们不建议你的太阳能电池阵列的大小，以产生更多的电力超过你预计每年使用.

西澳州法律要求PSE提供当前形式的净计量，直到达到州规定的参与门槛. Thanks to our net metering customers, we have nearly completed this requirement. We understand that customers may be concerned about changes away from our current net metering rate and program; and acknowledge the importance of planning ahead for energy management investments. PSE客户仍然可以互连并申请我们的净计量计划 150年计划. 如果实施新的太阳能费率或电价表以取代当前的净计量计划, 我们保证 minimum of 6 months' notice 在我们停止接受现行净计量计划的申请之前(附表150).

Customers can still apply to our current net metering program under 150年计划. 在进行任何更改之前，PSE将至少提前6个月通知安装人员和客户. We will also share updates on our website to the net metering program, 税率或关税, or if we stop accepting applications to the current net metering program.

向目前的计划提交完整申请的客户将获得额外的时间来完成系统的安装, without being removed from the program.

Batteries add backup power. 重要的是要知道，太阳能电池板本身不能在电网中断时为您的家庭提供能源. 在停电的情况下，太阳能系统会自动断开与公用电网的连接，以保护个人和修复人员的安全. 然而, 与太阳能一起安装的电池可以从电网或太阳能电池板上充电，然后在停电期间可以与电网隔离，为部分或全部家庭能源负荷提供电力. 电池为一个家庭供电的时间取决于电池的大小和房子使用的电力.

Batteries do add to the cost of a system, so it is essential to consider how much value the backup power has to you. PSE正在探索降低客户安装电池成本的方法，通过财政激励或动态费率设计，以换取客户允许PSE在高峰事件期间使用部分电池存储容量.
