When this incentive is applied to your project in Sales Mode, the savings will be calculated as a one-time payment applied to the total system cost. Note: If you do not have access to Aurora V1, please reach out to your Customer Success Manager or Support for assistance. You can also create your own Custom SREC Incentive. Then, select the appropriate incentive, change Disbursement Type to Lump Sum, and specify the percentage that gets paid out to the homeowner. To model for these correctly, admins will need to access Aurora V1 > Database > Incentives. However, some SRECs (most notably Illinois SRECs) are paid up front as a lump sum determined by the size of the system. Most SRECs are paid out incrementally, as in, via smaller payments over time. This will factor the expected monthly income from SRECs into their post-solar bill and the monthly savings chart. Once enabled, there will be a new item in the post-solar card on the Bill Overview page in Sales Mode for “Incentive income”. To show the effect of SRECs on the homeowners’ post-solar monthly bill, admins will need to navigate to Settings > Pricing > General and turn on the toggle for “Show recurring income for performance incentives”. hex file it matches what is calculated provided I change: FLASHEND. However, this is not factored into the monthly post-solar bill comparison. If I calculate the checksum of the produced. To apply these to your project in Sales Mode, navigate to the Adjust Pricing page > Incentives > then search for the incentive you’d like to apply.īy default, Aurora will calculate the total expected savings from the SRECs and subtract that amount from the system cost. DediProg User Manual 05/2018 Dediware Checksum Calculation Methods DediProg. Some SREC programs, like other incentives, are already modeled for you in Aurora’s Database section. If you are in a state that offers a rate of $260/ SREC, the total value of SRECs for their system would amount to $2,600. Of the states that offer SRECs, all have varying rates.įor example, your system generates 10,000kWh. The homeowner will receive credits based on how much energy their system produces, which they can then sell back to their utility company. And if you managed to prevent your bootloader from being bypassed, you can use it as a root of trust, and your microcontroller won't be running a single instruction that is not signed by you.Solar Renewable Energy Credits (SRECs) are an incentive for homeowners who have solar. Unless either someone got big enough a quantum computer, got way too much CPU cycles, or hacked your computer holding the private key, your bootloader won't accept anything that is not cryptographically signed by you. RSA-4096 and SHA-512 are both strong crypto. Instead the entry point and stack pointer of the bootloader is written there. To guard against incomplete uploads and TOCTTOU vulnerabilities, the Reset vector and initial stack pointer is not written to the Flash before the entire image is verified. If the hashes agree the image is accepted. An RSA-encrypted signature is then received, decrypted using the embedded public key, and compared against the calculated hash. After writing the firmware image to the flash, the SHA-256 hash of the image is calculated. The bootloader embeds an RSA-4096 public key that you have the private key of. ![]() while for other chips, maybe do not need enable, and also can place it in your own address. I would prefer a better technique using proper crypto. srec with CRC checksum file will under Debug folder: Pay attention: For the format of image header of LPC540xx devices, we need enable compute CRC and put the CRC value in the specific address.
